My newborn is 16 days old we are breastfeeding. The last few days she has started fussing, squirming, Unlatching and crying when nursing. Sometimes it’s from the start and other times it’s after a few minutes. I’ve tried burping her more in case it’s gas. I prop her head up when nursing and make sure she’s positioned on her side when we cross cradle nurse. She does not like any other positions. Could it be a growth spurt? Gas? It’s so frustrating and makes our feedings so much longer and I end up in tears. She always has milk on her face when we are done and it’s not just one boob she fusses on. Help
