Our son wanted to initially no pacifiers. I had tried several forms and manufacturers. He tended to thumb sucking and I wanted to absolutely avoid, I was persistent and had the smallest MAM pacifiers success. Have remained loyal since the mark and only the sizes have changed. He now needs only to sleep, but since then also equal to 3. One of the mouth and each one left and right in your hand. I am satisfied with the processing and form. As long as our little one does not want to sleep without, he gets the MAM pacifiers.
