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 loved these water cups for the longest time. With my firstborn we used the straw cups when he was read to start drinking water and it was the best decision and our favorite cups of all time! Now he is obsessed and loves this tumbler. The gentle flow makes it easy for him to drink water without spilling and the strap handle is his favorite because he easily gets to carry it around with him everywhere. It’s worth the investment and great quality! I love all the cute designs and how easy it is to clean.
