Title: Too leaky!
Review: I have used both the 4 oz. and the 9 oz. bottles to feed my 3 month old son, and the bottles are so leaky! The problem seems to have gotten progressively worse over time because now they leak to the point that I'm not sure how much my son is ingesting and how much is soaking his bib and burp cloth. I tried adjusting the nipple and tightening or loosening the collar - nothing has stopped the leakage. I have switched to Gerber New Traditions bottles with no problem so far. I gave this product 2 stars instead of 1 because the nipple shape is very similar to the real thing, and that's always a plus for someone who wants to combine bottle and breastfeeding.
Is the review positive or negative?
