Lu has always had a shallow latch. We worked through it but it's not a deep latch as I think she has a very strong gag reflex. She was doing a lot of gagging and choking in the beginning from OALD but also if the nipple was a little too far into her mouth. So in trying to introduce the bottle, I notice that she will gum the nipples and even begin to suck on them, but the minute it;s too far into her mouth she jumps and immediately starts crying, from surprise. So what to do now? All the nipples I've tried are pretty long. The only on she seems to like is the Playtex Orthodontic one, but it's still too long. Is there such a thing as a short nipple?
