Title: Hard to use
Review: I had high hopes for Avent bottles since I'm also breastfeeding and everyone swore they were the best. But the reusable bottles were just too hard to use. The bottom piece makes it nearly impossible to warm the bottle in hot water and forget about trying to push the air out of the bag. I just took them out. In the end I found that my baby took in a lot of air - I think it's just not the right nipple shape for him. Now they're just sitting in the cupboard and we've moved on the Dr. Brown's which are working great.
