Query: I HATE THESE (...)THINGS

Not only do they leak all over the place, the nipples don't fit properly (it's not you it's the nipple)They just plan (...)Also my son he did'nt like the nipple, it's nothing like my breast.So I ended up going to the store to see if I could find the latex nipple Avent does not make one!!! Go figure. I went online to see if the company would be of any help...NOT!!! So I ended up buying Gerber and Evenflow bottles and nipples...HE LOVES THEM.So my bottom line is...DO NOT BUY THESE BOTTLES....
