Perfect. Lovely size and weight. Used by our baby as an open cup from 6 months. Perfect first cup.

We bought first an open training cup, the tiny 2 oz one and our baby was happy with it. He learned very quickly how to drink from the little cup and also was using it a lot in unpleasant teasing time. The cup became one of his favorite teaser - lol, thanks to the cup thickness and super soft silicone it made of. The open cup was perfect for his little hands, but after a while 2 oz became not enough volume for him to drink and we decide to get bigger cup. Having excellent experience with the small cup, I decided to stick with Munchkin products and bought 4 oz Munchkin® C’est Silicone! Open Training Cup with Straw. It was the same great quality as the littlest open cup and the baby loves to use it. The only concerns are that baby learn very quickly not only how to use the straw to drink, but also how to pull out the straw to play with it and how to open the cup and actually baby is having a lot of fun doing so. We consider the cup not only as training cup but as well as a product stimulating baby's development and skills, and see a huge progress on what baby can do using his little fingers. Also note that the cup is not exactly spill proof when dropped to the floor. It might be a little inconvenient for parents, but could be another learning curve for a baby. Overall we just love both Munchkin cups and highly recommend them. They are definitely high quality, nicely designed, very functional and just right for the little hands.

The first two times my 8 month old used this straw cup she struggled a bit with getting too much liquid (coughing/sputtering a bit), but then by the third time she had it figured out and can now use it like a pro. The cup size is great for little hands and once she's ready, we'll be using it as a first open top cup. The straw is not valved, so it will spill if it's tipped, but that also means baby isn't getting used to having to suck against a valve. It's super easy to clean and my regular sized straw cleaning brush fits inside the straw. Update: my baby is now about 13 months and this is a great open top learner cup.

My daughter learned to drink from a straw using this cup. I find it better than the cups that are spill proof. Has some good weight to it and easier to clean.

I got this to teach my 5 month old to drink from a straw since she wasn’t a fan of baby bottles and it worked great. it’s not spill proof because of the straw but it’s fully sealed between the lid and cup so spills are minimal. It has some weight to it so it was a bit of a struggle for her to hold it at first but otherwise love this as a beginner straw cup!
