Bottle Nipple - back to level 2

After changing the nipple to a faster flow, I noticed that Julia does not finish her bottles anymore. She also has alot of air and needs to burp more often. In fact, it was getting more and more difficult to get her to drink milk. I can hear her gulp every time she swallows and she takes smaller sucks to compensate for the larger amounts of milk getting into her mouth. Not good.

I made an executive decision to revert back to using level 2 nipples. As soon as I did this, Julia finished the next 2 bottles. Hooray!
