for the most part my 2 year old can drink out of a regular cup if it is filled half way. but sippy cups are still best because he always seems to be on the go. im not sure what brand but i think it is playtex and three of them have mickey mouse and one of them has pixar cars. the straw comes in two parts, the bottom is hard and it fits inside the top which is soft and plugs into the lid. he has this bad habit of biting the straw and i had to throw away 2 of the 4 soft straws. can anyone let me know what brand of sippy cup would be best and possibly what store to get it from?
