Switching to new bottles

We have been trying different bottles since we brought Aaron home from the NICU. Aaron is such a good baby and doesn't seem to mind the different nipples on the bottles. It seems like he likes the nipples on the Momma bottles and the Similac disposable nipples the most.  He's really not a picky baby as I have heard that many parents keep trying to find the bottles their babies like.

As Aaron has been able to take more milk (sometimes 5-6oz a feeding), we have to switch to bigger bottles with faster flow nipples. We decided not to go with the bigger Momma bottles as they are a pain to warm the milk with the bottle warmer. I changed all his bottles to Dr. Brown's in hope that will help with Aaron's gas and colic issues, even though there are a million pieces to clean with these new bottles. So far, Aaron seems to be okay with the new nipples and take them just fine.

This is what happened after switching to the new bottles
