I love the Avent product line . since I last use they , they have definitely improve . with the new ring that hold the nipple in place , I do not have any issue with the bottle leak . this be a very nice surprise and a change that I do not mind complete a extra step for . as usual , they hold up great and limit the fussiness . the pacifier cover be lifesaver since I hate put they into the diaper bag without protection . with the cover , I no longer have to put the pacifier into a ziplock bag to keep they clean .
