We’ve been using the Dr Brown’s Anti Colic bottles but they have been leaking like crazy since we got them 2 months ago & I think we’re reaching the point where we’re just beyond annoyed with it. Plus my son needs to upgrade to 8oz bottles anyway. Are there any similar bottle to dr Brown that DONT leak? Or just any bottles you ladies have absolutely loved? For the mean time we’ve been using the spectra bottles & he doesn’t seem to mind that the nipple is wider than that of the dr browns bottles so we’re open to trying one with a wide nipple as well.
