The next size up from the 5oz training cup. This 9 oz (270 ml) silicone cup holds a full toddler-sized drink of milk, water or a smoothie under a lid with a soft silicone straw.

Keep the lid on in the car and on outings – the tapered base fits most cup holders – and lift it off at the table so your toddler can practice drinking from an open cup.

Frequently asked questions

Is the 9oz cup good for milk?

Yes. It is made for water, milk and smoothies, and the cup, lid and straw all separate for top-rack dishwasher washing after a milk day.

Does it fit a car cup holder?

Yes. The tapered base fits most standard car and stroller cup holders.

When should my child move from the 5oz cup to the 9oz?

Once they are 12 months or older and regularly empty the 5oz cup in one sitting, the 9oz cup gives them a full drink without a refill.

Is it spill proof?

It is spill-resistant with the lid on, but the straw has no valve, so it is not fully leak-proof when tipped over or shaken.
