Title: Avent = Gas problem
Review: I started using these bottles prior to going back to work, wanting a bottle similar to the (...). My daughter took the nipple, no problem. I didn't have a problem with leaks...as everyone else noted, you just screw the nipple ring on lightly and assemble the nipple and ring while wet...that's all it takes. I do however have a problem now with terrible gas build up in the evenings and gas noises that make my husband blush!!! . You moms know the screams of a baby with gas build-up...it's awful. I had been using gas drops, but wanted a solution and not a quick fix. I switched to the Dr. Brown's bottles and she hasn't had the painful gas since!!!
