My favorite bottle for my newborn. I was passionate about no plastic bottles and I’ve tried a number of different options and these are by far the best. I’ve had no issues with nipple confusion either and he switches back and forth between pumped bottle milk and breastfeeding. Highly recommend these and the 8 oz bottles are on sale right now!
