Is choking while breastfeeding dangerous?

Hi, i have 2 week old baby who often chokes when breastfeeding (1x per session), he would choke (cough, but not losing breath) and pull his head from my breast after that. I usually use craddle position and also use a nipple shield (because i have short nipple). Is it dangerous? What caused him to choke? What should I do to prevent it? Is bottlefeeding better to prevent choking? Thanks in advance, i'm really worried #1stimemom #firstbaby #advicepls #breasfeedingmom
