I breastfeed my DS who has GERD, but now and then I need someone else to feed him. Sometimes he’ll take an ounce or so of breastmilk from a bottle, but mostly he just chokes, spits, gags, squirms and cries at a bottle. It seems to me that it just comes out too fast for him. I’m using Avent newborn bottle nipples. Avent doesn’t make anything slower than that. Are there special bottle nipples out there that are SUPER slow?
