Just great the hat! Slightly moisten, stick to the chest and there you go. Then simply rinse with a little fit and then, of course, clean water. For those in which breastfeeding without not only goes to suggest the baby can then later easily get used to the bottle. But I would buy it next time equal in size L, even if was recommended to me in the hospital south. But it hurt sooo because when vacuuming not the entire areola has fitted into the nipple. With L but had a relaxed breastfeeding guaranteed.
