I used the platex nurser set with all 3 of my babies. I love that I can dispose of the drop in liners. I tried the plastic bottles and hated that after a while no matter how much you washed it, it will still smell awful. I hated having to scrub with the bottle brush and not be able to get every little thing in the inside of the bottle. You don't have to worry about anything but cleaning the tops and nipples. There are also a variety of nipples to choose from for different ages. There are silicone and latex nipples available as well. These bottles have been around for years. My mother used them...
