I must say as a new mom there are a few things I wish I never bought. But of course this was my first child and people learn! Aside from the do nots Rhee are the must ! My daughter wouldn't take any pacifier which drove me crazy. Although I was always against pacifiers. My baby started sucking on both of her fists trying too put both in her mouth at once. I finally got this product and boy am I, a happy mama !
