My bottles weren't leaky. At first I thought they were, but then I realized that my son was sucking the milk faster than he could swallow and I just adjusted the way I held the bottle for him and I didn't have any other issues.
I love avent products!!! I am a mom of two, breastfed both. I had no issues with nipple confusion because of the way these are shaped.
