Baby takes the nipple easily and only having to sterilize the nipple makes life so much easier also one bag for pumping and bottle saves so much time, so happy
We love this set. My son locked right onto the nipple without any playing or frustration. He seems to prefer this to the other 5 styles we have tried. After a two week study, we determined that our son spits up the least with the Kiinde bottles. _x000D_ _x000D_ The only things I would change with this set is to add a base for the bottle or make it so the cap from the nipple can lock into the outer shell. Also, I would add 2 nipples of each size as parents of infants don’t always have a chance to get the nipple washed right after a feeding.
