When I heard about BPA, an additive in plastic that can be found in baby bottles and may cause harm, I decided to trade in my old bottles for new BPA free bottles. The FDA has yet to ban the use of BPA but I'm still a cautious mom and decided I didn't want to take any chances just in case. I decided to try Avent bottles. The Avent bottles that are BPA free are the Tempo line.
This line of bottles uses disposable liners. This way you avoid having to boil the plastic parts of the bottles so there is no chance of BPA leaking out. This is very convenient since after each feeding you only need to wash the nipple and the part that attaches it. However, you will also need to buy liners which is more money spent, and you will need to remember one more thing to bring on outings which any mom knows we need to remember enough already! The main thing that bothers me about the liners is that it isn't very environmentally friendly, its just more trash to throw away. But being a breastfeeding mom I only use these bottles occassionaly so it isn't as bad for me.
The bottles are $9.99 whether you want the 4oz size or the 9oz size. The box of liners for the 4oz bottles is $4.49 for 50, and for the 9oz size they are $7.99 for 100.
I'd say these bottles are worth a try for moms who only use bottle occassionally. I wouldn't suggest them for moms who use bottles at every feeding because of the trash factor and the fact that you have to buy liners.
