Am I the Only One with This Sippy Cup Problem
My son is now 1 and his doctor told me to switch from bottle to sippy cup. We have been using the Nuby sippy cup for water and it really hasn't been that great. The tip seems to sink in every time he drinks from it. I have to grab it and squeeze the tip to let air in and the tip returns back to normal. This happens every time he drinks from it. Do all Nuby cups do this? Are there other sippy cups you recommend that are better for my son to drink his milk in? Please help :)
