Baby Milk Bottle Steriliser vs Steamer

1. If the bottles are glass, should be okay to reuse, buy new teats. If bottles are plastic (which they look like they are), I would suggest getting new ones too. I suggest buying just a 2-4 bottles to start because babies take to different bottles differently. My baby used to gag /cough on Philip avent bottles because the teat flows a tiny bit faster than say Mam bottle, even though I used the slowest teats for both. 2. It's a steam sterilizer for milk bottles! I use it for milk bottles and breastpump parts. So far meet my needs. 3. I'm not sure if you're referring to UV sterilizer. I personally didn't get UV as I am not planning to sterilizer other baby items. If you are planning to, and might want dry bottles after each sterilization, you should consider UV sterilizer.
