Anyone use them? Do they fit Born Free bottles? My DD is starting daycare in 2 weeks & all of a sudden today started to refuse the bottle. I exclusively breast feed but try to give her at least one bottle of breast milk a day. I am thinking the Nuk pacifier that she loves dearly has made her dislike other kinds of plastic nipples b/c she sucks on the pacifier way more than the bottle nipples! Any suggestions?
