This is why you don’t stock up on one type of bottle before baby is born
My baby is breastfed. For my first I exclusively pumped and she took the Dr. Browns bottles no problem. We had a few different ones from her so we figured our second would take one of the four different ones we already had.
Nope

Here you will see me packing up Dr. Browns, tommee tippee, avent, mimijumi, comotomo, NUK naturals, MAM and Munchkin latch. I’m sure there were others but we lost them. You know what finally worked? A bottle I found on clearance at the grocery store. The playtex nursers with the drop in liners.
So when buying for your baby, I suggest purchasing one of each bottle. Don’t just stock up on one kind just because your best friend used the same one. And what works for one of your babies may not work for the next one.
