How do I choose the right cup size?
If your baby is new to straw cups, the shorter 200ml size is often easier for them to handle. For basic use like water or small quantities of liquids, 200ml is sufficient. If your child drinks more or if you plan to fill it with milk or other beverages, a 300ml cup is recommended.

We have been using the small size straw cup for 15 months and my boy loves it. This is the only cup that is truly leakproof. We needed the bigger one for 21 months old now so I bought two of them.

Love this cup! I truly do! It'ss cute and doesn'st spill, which is nice! The lid is easy to open and close, my only thing I wish was different is the handles. They move very easily and I just personally wish they stayed in place. But so far it hasn'st seemed to be an issue with my daughter who is 15 months. So overall, highly recommend

This is my third purchase because we love these cups so much! They never leak and the rotating handle makes it so easy for my daughter to hold and use! We love the larger size for her milk and the smaller size cup for water! 10/10 quality
