I have been using the Dr Browns bottles since LO was 5 weeks - as the TT anti-colics are just the pits of the earth. Now LO is now grabbing for his bottle and he is past the colic stage, but I love my Dr Browns bottles but I can't exactly inform my LO that he needs to tip the bottle up past the blue vent so it doesnt leak!!!! LOL So I wonder are there any mummies out there which have been faced with similar situation. I want to move onto a different bottle so that LO will be feeding himself soon. But which one? He's now 5 months.I have heard that the Avent are good. Advice and recs please? Thanks!
