I do not put the average because the nipples have served until my baby started having reflux problems ... And impossible to drink thickened milk! Even the nipple 2 was not the case! I had the bad idea to enlarge the holes, he drank too soon after. In the end I opted for bottles of Mam brand, nipple leaves to spend the thickened liquid baby is much calmer drinking. In addition even with normal milk, I found all my bibs always sals. With mam bib makes me much more time!
