Avent Infant Feeding Set —
I used these bottles for my first son, but switched to the Gerber ComfortHold when my second son came along.
With the Avents, I liked the shape and size, and the nipple seemed agreeable to my son, but I had so much trouble with them leaking. They are persnickety. If you put the lid on too loose, they leak; if you put them on too tight, they leak. You have to be careful to tighten them just right. Annoying! I'd recommend the Gerbers - they rock.
