Once the bottles are behind you, the sippy cups begin. And with them, a new set of labeling questions — because sippy cups and toddler food containers are a different kind of labeling challenge than standard baby bottles. Smaller surfaces, more variety in materials, and a dishwasher that runs every single night seven days a week.
Most parents assume the same label that worked on the baby bottle will work on the sippy cup. Sometimes it does. Sometimes the cup is a different material, a different shape, or has a silicone body that nothing sticks to regardless of how carefully you apply it. And the container that goes to daycare every morning still needs to comply with the same labeling requirements as everything else — name, date, and contents visible before anything is opened.
This guide covers everything specific to sippy cups and toddler containers: which surfaces hold labels through nightly dishwasher use, how to handle the silicone cup problem, the lid rule, size matching, and the prep sequence that determines whether a label lasts weeks or years.

1. Sippy Cups at Daycare — What Providers Need on the Label
Sippy cups go through the same labeling requirements as baby bottles at most licensed daycare and childcare facilities. Even as your child transitions out of bottles, the identification and date requirements stay in place — especially in infant and young toddler rooms where multiple children are drinking similar cups with similar contents at the same time.
Standard information for sippy cup labels at daycare
- Child's full name — first and last
- Date — when the cup was filled and sent
- Contents — water, milk, formula, juice. Particularly important in rooms with children who have dairy or other food allergies.
2. Sippy Cup Surfaces — What Holds Labels and What Doesn't
Sippy cups come in more material and shape varieties than baby bottles, and the surface is what determines whether a label bonds through nightly dishwasher use or peels off by Tuesday.
Surfaces that hold labels well
- Hard plastic body — the most reliable surface. Clean with alcohol, dry, apply to the smooth upper body nearest the spout. Labels on hard plastic hold for years through daily dishwasher use when applied correctly.
- Stainless steel body — excellent when prepped properly. Stainless holds oils and fingerprints — wipe with alcohol every time before applying. Once applied correctly on a clean surface with full cure time, stainless labels are very durable.
- Hard plastic lids and spout assemblies — the smooth outer panel of a hard plastic lid or the flat face of a flip-top spout lid bonds well. Use a small label sized for the lid surface.
Surfaces that don't hold labels
- Silicone bodies — non-stick by nature. Nothing bonds to silicone reliably. See Section 3 for the solution.
- Textured grip surfaces — raised dots, ridges, or molded grip patterns prevent full adhesive contact. Labels cannot be applied to textured surfaces. Find the smooth area on the cup, or use the spout assembly.
- Soft spout and straw material — the soft silicone or rubber tip of a straw cup or spout is flexible and non-stick. Never apply a label to any soft flexible component of the cup.
3. The Silicone Sippy Cup Problem — and the Solution
Silicone is a non-stick surface by nature — it's the same property that makes silicone bakeware release food so easily. No adhesive label will bond to a silicone cup body reliably, regardless of how carefully it's applied or prepped. This isn't a label quality issue. It's the material.
Popular toddler cups made entirely or primarily of silicone — soft-bodied squeeze cups, flexible straw cups with silicone sleeves — present this problem consistently. Parents apply labels to the silicone body, the labels peel within a few washes, they try again, same result. The material won't hold.
The solution — find the hard plastic component
Almost every sippy cup with a silicone body has a hard plastic component somewhere — a lid ring, a spout collar, a handle attachment point, or a base ring. These are the smooth, stable surfaces that bond well. Apply your label to the smoothest hard plastic component available. For most silicone-body cups, the lid assembly has a hard plastic outer ring or face that works well. Use a small label sized for that surface and clean with alcohol before applying. If there is genuinely no hard plastic surface anywhere on the cup, label the lunchbox or cup carrier that the cup travels in rather than the cup itself.
4. The Lid Rule — Always a Separate Label
Every sippy cup lid needs its own label, separate from the body label. Sippy cup lids detach completely from the body — during washing, during the mealtime rush at daycare, and when a toddler figures out how to pull the lid off, which happens earlier than you'd expect.
A labeled body with an unlabeled lid is half a system. In a daycare room with multiple children on different drinks, a mismatched lid — a milk cup lid on a water cup body — matters. Label both pieces before the cup goes to daycare the first time, and maintain both labels throughout the life of the cup.
Lid label placement for sippy cups
- Use a small label sized for the flat top or smooth side panel of the lid — not a standard rectangle that overhangs the lid edges
- Place on the flattest smooth area: the top of a flip-top lid, the smooth outer ring of a twist-off lid, the flat face of a snap lid
- Clean with alcohol before applying — lids go through the dishwasher and accumulate soap residue that prevents adhesion
- Never apply to any flexible or soft component of the lid — the label surface must be hard, smooth, and stable
5. Label Sizing for Sippy Cups and Small Containers
Sippy cups are smaller in diameter than most baby bottles, and toddler snack containers range from very small round containers to flat bento-style boxes. Label size matching matters here more than with larger items — a label that's too wide for the surface will curve around the body and lift at the edges immediately.
The flat-lay test
Before peeling any label, lay it flat against the surface without removing the backing. If the label lies completely flat with no edges curving away from the surface, the size is correct. If the edges bow up from the curved body, go smaller. This two-second test prevents the most common size-related application failure on small cups and containers.
General sizing guide for toddler items
- Small sippy cups (6–9oz) — use a small or extra-small label on the body. A standard rectangle is often too wide for these narrow diameters.
- Medium sippy and straw cups (10–14oz) — a small label works on most. Do the flat-lay test for the specific cup.
- All lids — always use a small label regardless of cup size. The flat area of most sippy cup lids is significantly smaller than the body.
- Small snack containers — small label on the smooth side panel. A standard rectangle often overhangs the edges on round containers under 3" diameter.
6. Application Sequence — Prep, Press, Cure
The prep sequence for sippy cups and toddler containers is identical to bottles — and equally non-negotiable. The most common reason labels peel from sippy cups and containers is the same as for bottles: the surface wasn't cleaned with alcohol before applying.
The correct sequence — every time
- Clean the application area with alcohol — wipe firmly with alcohol on a cloth or cotton pad. Even brand-new cups have manufacturing oils on them. Let the surface dry completely.
- Apply to the clean dry surface immediately — don't handle the cleaned area with your fingers before applying. Hand oils transfer immediately and undo the prep.
- Press firmly from center outward — work from center to edges, pressing every part of the label surface against the cup. Run your thumbnail along every edge for full contact.
- Allow 24 hours before the first dishwasher run — the adhesive cures for up to 24 hours after application. Label cups at least the night before they go to daycare — not the morning of.
7. Toddler Food Containers — The Same Rules, Different Shapes
Toddler food containers — snack cups, divided plates with lids, small food jars, squeeze pouches, bento boxes — follow the same labeling principles as sippy cups. The surface rules are identical: smooth hard plastic or metal bonds well, silicone doesn't, textured surfaces don't. What changes is the shape and the label placement.
| Container Type | Label Placement | Notes |
|---|---|---|
| Round snack containers | Side panel — upper smooth area. Lid top — flat surface. | Label body and lid separately. Use a small label on the lid — sized for the flat top, not overhanding the edges. |
| Bento-style flat containers | Flat side panel on body. Flat top or side of lid. | Flat rectangular containers have more label surface area — standard label size often works on both body and lid. |
| Small food jars and pouches | Upper smooth panel on body — nearest the lid. Lid top or outer ring. | Place label near the top, away from the base where jars sit in wet surfaces. Label both pieces separately. |
| Silicone squeeze pouches | Hard plastic cap only | Silicone pouch body — nothing sticks to it. Label only the hard plastic cap. If no hard cap exists, label the storage bag or container the pouches travel in. |
| Divided plate with lid | Underside of plate rim — smooth area. Lid top or side. | Label both the plate and the lid separately. The underside rim area of most divided plates has a smooth surface that bonds well. |
8. Transitioning From Bottles to Sippy Cups — Labeling the Changeover
The bottle-to-sippy-cup transition usually happens gradually — some bottle feeds replaced by sippy cups while others continue, then a full switch. From a labeling perspective, the changeover is straightforward: sippy cups follow the same labeling requirements as bottles for daycare, and the same label product covers both.
What changes during the transition is the container type and size — which affects label sizing. If your bottle labels are sized for a standard baby bottle diameter and your new sippy cups are narrower, you may need a smaller label to avoid overhanging the edges. Do the flat-lay test on each new cup before applying.

Frequently Asked Questions
My sippy cup label keeps peeling after a few days. What am I doing wrong?
Almost always one of three things: the surface wasn't cleaned with alcohol before applying, the cup was washed before the 24-hour cure time, or the label was applied to a silicone or textured surface where no adhesive will bond. Check the cup material first — if it's silicone-bodied, find the hard plastic component and apply there. If it's hard plastic, clean with alcohol, let dry completely, apply firmly, and give it 24 hours before washing. A label applied correctly to a prepared hard plastic surface should last years, not days.
My child has a popular straw cup with a silicone sleeve covering most of the body. What do I do?
Find the exposed smooth hard plastic or metal above or below the silicone sleeve and apply there. Most popular straw cups have a smooth plastic or stainless neck area above the sleeve where labels bond very well. If the sleeve genuinely covers the entire body with no exposed smooth surface, apply to the smooth outer area of the lid assembly instead. The lid needs a label anyway.
Can I use the same labels for sippy cups that I used for baby bottles?
Yes — the same waterproof label product works on all smooth hard surfaces. What changes is the size. If your bottle labels are sized for a wider baby bottle diameter and your sippy cups are narrower, use a smaller label that lies flat on the smaller surface without the edges curving away from the body. Do the flat-lay test before applying to each new cup.
Do sippy cups need the same information on the label as baby bottles?
Most licensed daycare facilities apply the same labeling requirements to sippy cups as baby bottles — full name, date, and contents — especially in infant and young toddler rooms. As children move into older toddler and preschool rooms, requirements sometimes relax to name only. Check your specific facility's handbook. Our write-on labels can be configured for whatever combination of fields your daycare requires.
My child is at home now — do sippy cups still need labels?
For home use only, labels are a personal choice. Many families label anyway because toddlers take cups everywhere and cups show up in surprising places. The more practical answer is: if the cup will ever go anywhere other than your house — daycare, grandparents, a friend's house, preschool drop-ins — label it. The label is there for the moment the cup leaves your direct line of sight, not just for the regular daycare routine.
How do I label a 360-degree sippy cup with no obvious flat panel?
Most 360-degree cups have a smooth band around the middle of the body between any textured or grip areas — that's your label zone. Use a small label and do the flat-lay test on the smoothest available section of the body. The lid of most 360-degree cups has a smooth top or outer ring that labels well. Apply one label to the smoothest area of the body and one to the lid. Clean with alcohol before both applications.
