my daughter was fully off of the bottle by 4 months. she kept crying for my nephews sippy cups so her dr told me to try it and when we did she never wanted the bottle anymore.

I got it at heb! From a grocery store. :)

I try giving m son a sippy cup he doesn't like it or maybe I'm not giving him the right one! his a year, where did you get your sons sippy cup at?! @tobias123
