I like these, because the milk only touches silicone, and never on plastic. I love that I can sterilize it and boil it without worrying about plastic melting. It doesn't have too many pieces to clean unlike Dr Browns and doesn't leak. The collapsing silicone keeps air out so less spit up and good for colicky babies! The nipple mimics natural feeling and helps babies latch so good for breastfed babies. Make sure you get the right nipple flow for your baby! I'm starting with zero - extra slow flow nipples for my newborn. Baby registry must have, baby meal time, target, amazon, silicone baby bottle breastfed frienedly #LTKMostLoved
