I currently have been buying a few bottles when I can get deals. I've gotten a few that were free samples and some that I purchased. I bought the glass tommee tippee 9oz when they were on a bogo sale. I want to try the Joovy Boob glass 8oz, but they're like 15 bucks a bottle. Apparently, they're supposed to be fantastic for breast to bottle fed babies. I plan to use a 10% coupon and my Babies R Us Rewards (about 10 bucks). Anyone have any experience using them? Any other opinions on bottles are welcome. I only buy glass bottles and I don't want to use Doctor Browns because of all the crazy parts!
