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.

This is the only bottle that we were able to find that truly is spill proof while also allowing you to sip through the straw effectively. My only knock on it is that the straw usually sits on on side of the bottle so unless you have the bottle rotated in that direction while drinking you can'st get any liquid out of it when it'ss getting toward the bottom of your drink.

My 16 month old daughter loves being able to open and close the flip-top on her own and I love that it doesn'st leak when she plays with her bottle! Great straw and easy to clean. 10/10 highly recommended.
