Query: Terrific bottle

We started out with the regular Playtex drop in bottles but our baby would always seem to end up with to much air in her belly. My husband came home with this bottle one day and I shrugged it off for about a month. I am also breastfeeding and was skeptical if it would work as well. I wish I would have used it earlier! Immediatly I saw results and had a wonderful, gas free baby. Now she keeps down pretty much everything and is able to let off her own effortless tiny burps. The special nipple is a wonderful invention that dosen't let any outside air in. We even have the 8 ounch ones which are just as good. I ghighly recommend these bottles! A+ in my book.
