Negative Positive
Title: Sometimes they leak, sometimes they don't
Review: I, too, have experienced the bottles leaking, which is very frustrating at 3 in the morning when you are half sleep and feeding the baby by a nightlight. The bottles do not leak around the nipple (which is what I think one mother thought when she mentioned that it leaked b/c she didn't put the nipple in correctly) but it leaks from the base that you screw onto the bottle. I can't figure out exactly why they do this occurs because I have screwed them on tight everytime. Great bottle, but they are hit-or-miss with the occasional leaks.
Is the review positive or negative?
