The Munchkin It's Silicone! Trainer Cup with Straw is a soft silicone straw cup designed to help little ones move on from the bottle or breast and start practising with a cup. A clever two-piece valve lets liquid flow through the straw when your baby draws on it, so early sippers can get to their water or milk without much effort — making it a useful first cup for the stage where drinking skills are still developing.
What sets this trainer cup apart is its convertible, two-in-one design: it works as a lidded straw cup and, once the lid comes off, as an open cup, so it can grow with your child as their drinking changes. Made from 100% food-grade silicone in a pastel teal with a two-tone contrast, it's gentle on delicate gums, soft enough for small hands to grip, and sturdy enough to stand up to a bit of squeezing.
Built for the bottle-to-cup transition
The lightly weighted base helps keep the cup steady and is designed to reduce tipping during those first wobbly sips. The lid fits snugly so it's removable by a grown-up rather than baby, which keeps sipping splash-free while it's on. It's versatile too — handy as a snack cup as well as a sippy cup — and holds 118 ml (4 oz), a practical size for water or milk on the go or at the table.
How it works
- Two-piece valve: The valve in the straw lets liquid flow through easily when your baby wants to drink, so it doesn't take a lot of suction effort to get started.
- Convertible design: Used with the lid and straw it's a free-flow straw cup; with the lid removed it becomes an open cup, letting you follow your child's pace as they progress.
- Weighted base: The lightly weighted bottom lowers the cup's centre of gravity, which helps it stay upright and cuts down on tipping.
Materials and cleaning
The cup is made from soft, 100% food-grade silicone and is free of BPA, BPS and PVC. When mealtime's done, it's top-rack dishwasher safe, so it slots into your usual routine without extra fuss.
Best For
The Munchkin It's Silicone! Trainer Cup with Straw is a great option for parents who:
- Are moving a baby of 6 months and up on from bottle or breastfeeding and want a first cup to practise with
- Like the flexibility of a cup that works as both a straw cup and an open cup
- Prefer a soft silicone cup that's gentle on gums and easy for little hands to hold
- Want something quick to clean that's top-rack dishwasher safe
It may not be the best fit if you:
- Need a fully sealed, closable bottle for a nappy bag — the lid is splash-proof rather than leak-proof
- Want a larger capacity than 118 ml (4 oz)
Disclaimer
Suitable for babies 6 months and up. Cup practice is a skill that develops over time and always needs caregiver supervision; readiness varies from child to child. If you have any concerns about your baby's feeding or drinking, please speak to a healthcare professional.
