My 2yo will drink water,juice etc from any sipper or a normal cup,but would only have her milk from a bottle.I was getting worried about her teeth so though this would be worth a try and it worked! It really is pretty similar to a bottle but a step in the right direction. I already had the bottles which by the way are unreal,so i got the sippy cup conversion kit which saved buying a whole new cup.These never leak,even if left upsidown on the couch which is great! Easy to clean as there are no extra valves etc.Cant fault it,have only been using the spouts for a week so hopefully they dont start leaking as they get older.
Doesnt leak,can just upgrade your bottles,bpa free,easy to hold,with or without the handles
