Rating : - Great Bottles
Bought them because all the reviews saying it would reduce colic. They sure do. My only problem is that it has so many pieces = a lot to wash. Funny thing - A few times, when I am half asleep I would forget to put the flange on the bottom, then try to fill the bottle. Oh what a mess.
