When I stopped nursing my son at 4 months I started researching bottles. While pregnant I always assumed I would use Playtex Ventair bottles. They are available everywhere! The more I research though, I found I liked the Mam bottles. They also caught my attention as they were on huge display at Babies R Us. They are BPA free, come in different colors and are very easy to clean.
My son had no problems with the Mam bottles. He never had any problems with gas. I felt that the nipple was easier for him to take compared to some of the nipples on the Playtex bottles. It also seemed like the nipple was closest to the breast.
Even though they are easy to clean, the bottom does unscrew and it can leak sometimes if you don't have it screwed on tight.
I will definitely be using these for any future children that I have. I was so so sad to take my son off the bottle and we tossed them. I really wish that MAM would make sippy cups and other feeding tools.
