Dr. Brown's Natural Flow Baby Bottle Review

Although I feel the concept of Doc. Browns bottles is  a good one the difficulty in keeping all the parts together and clean did not appeal to me.  I have used these bottels a few times for gas/colic and there was no diff. it how our baby was feeling.  After several months the parts became clogged and difficult to clean, I also lost the cleaning brush and parts to the bottle itself.  Granted I was using these with newborn twins so maybe that is why I lost a lot of parts (sleep deprived and all) but it still wasn't worth the hassle.
