For those of you who know Michael well, you know that the sippy cup has been a challenge. He will drink from any sippy cup you give him, but you have to hold it. He doesn't realize that he has to tilt his head back to get water from it! Well, I decided to get the kind of kid cups with the built in straw. He does beautifully! I wish I had thought of it ages ago! I am sure that I will hear somewhere in the next week many reasons to NOT use these cups with a 9 month old, but until then, I am using it!
