Avent Baby Bottles Review

I am an die-hard Avent product user because of the way their items are made for multiple purposes.  I have nursed/bottlefed all 3 of my children and this is the only bottle I use because the nipple let me switch easily from breast to bottle and back again without any problems.  The bottles are wide mouthed, easier to clean and fill and fit with the pumps perfectly.  I am also impressed with the fact that the bottles can be turned into a sippy cup with just the change of a nipple and adding (or not) a handle.  As for leaking, I found that if you dont over tighten the nipple ring then they dont leak.
