Query: Good Bottles

I've tried platex disposable, regular bottles, and avent. This is my second child. The first being 10yrs old. I love the shape and size of the Avent bottles. Easy to hold and big mouth openings. I started having trouble with nipples leaking and thought maybe I had over boiled the nipples so I bought more. Then sometimes they would leak. What I discovered is that if one begins to leak I remove the nipple and then then reinsert it and it takes care of the problem. Evidentally when you put the top together when it is still damp it doesn't always make a good seal. Since I've figured that out I have no trouble with leaking any more and I do love the bottle.
