Born Free Bottles
For those of you who use the Bornfree bottles - do you have problems with the nipples collapsing? I am disappointed in the ease of use with these bottles as there are several parts and it is never easy to simply warm-up a bottle. Now, the nipples push in about half the time she is sucking. She is using the right size nipple so I know that isn't the issue. I noticed that the rubber is very thin so I wondered if it was because of that? I feel like, for the amount of money I spent on the bottles...they should work. Anyone else have this...
