Another good product from Munchkin
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.

Great cup
Great cup for a baby or young toddler. Sturdy, soft, comfy for my almost one year old to drink out of. The straw is good. If he tosses it, it will leak but not completely dump liquid all over the floor. I would buy it again.

Great alternative
This is a cute little cup. It holds about 1/4 C of liquid. It is small enough my 10 month old can wrap her hands around it and hold it. It doesn’t have handles which I like.It does spill easily but the top stays on well and is acceptably resistant to baby fingers. All the leaking happens from the straw spot. We use it for water due to spillage.I mainly bought it for moving away from a bottle and learning to drink out of other types of cups. I use it as a cup and with the straw just in the high chair. I don’t think we will ever travel with this.It washes up well, we hand wash this only. Never been put in the dishwasher.

Great for learning
We love these versatile learning cups. Soft silicone straw, then remove the straw and top for learning to drink from a cup. Easy to clean. Needs supervision as it's not completely spill proof.

Great for learning to use a cup
Perfect little first cup.

Adorable and practical (but yes, babies will rip the straw out with glee)
Love the look of this cup and the size is really perfect for little hands. Very simple to clean by hand or in the dishwasher. I also really like the weight of this cup - it's not super flimsy, it has a good heft to it. Being able to use it as a straw cup or open cup is really nice. If you're looking for a cup that won't lead to a mess, this isn't it though haha. Little hands love taking the straw out and shaking the cup to their heart's content. If you're only putting water in this cup like I have, then this isn't a big deal at all, but don't wonder why your white carpet has a massive juice stain if you put juice in this instead.

Great starter cup but messy
This cup is so cute! It’s easy to clean and fits perfectly for my 6m old. The downfall is that even though the straw has a larger bottom it is very easy to pull out of the cup and the contents of the cup spill quite easily. Overall think it’s a great first cup to introduce you just have to be mindful of the mess

Perfecto!
Es pequeño pero se siente muy bien en la mano, tiene peso y cabe en las manitas del bebé. Se puede apretar ligeramente y no pierde la tapa, fácil de lavar y el popote tiene un tope para que el bebé no pueda sacarlo fácilmente del vaso.Pensé que tardaría mucho en aprender como funciona el popote por primera vez pero sin problema aprendió él solito cuando le di el vasito, lo mordió un par de veces y ya le dió sorbitos, así que siento que es muy facil de usar y, lo más importante, no lo lastimó por tener rebabas o ser demasiado duro.No tiene olores a químicos como otros que he comprado y se ve de muy buena calidad.

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

Love this cup!
My 11 month old doesn’t like solids so we weren’t holding our breath that she would want to drink from a straw. However, when I put some breastmilk in this and gave it to her, she figured out how to drink out of it in a matter of minutes!! We were so surprised!! I think because the straw resembles a teether? Regardless, love it. The cup is weighted which helps give them the correct sense of importance when holding a cup. It’s not leak proof or even spill proof, but if you’re watching your child closely at their highchair you can pick it up quickly and avoid too much spilling. It’s also so cute!! Will be buying a second one for sure

Good first cup/straw for teaching baby/toddler!
I love that it’s so simple to clean and it’s the perfect size for my 1 year old. It’s not fully spill-proof though (it leaks if turned on its side) but compared to other silicone cups it’s pretty good!

Good for teaching babies to use straw
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!
