i have used playtex bottles with all my children. i love the price. they are easy to clean and easy to feed with. the larger nipple allows me to go from bottle feeding to breast feeding without nipple confusion. the nipple are sold at many places so they are easy to replace. there are both girl and boy designs. and there are different sizes. they come in sets and are sold in singles as well. so if you wanted to try one out on your baby before you buy a whole set to be cost effective you can. the whole bottle comes apart so that you know you are getting the entire bottle clean. i tried many bottles...
