Babies do that a lot. They are always very uncomfortable until they pass they burp or poop after eating. I’ll say keep patting the back and keep them in straight position until they are relieved. Sometimes I hold my new born.facing down while patting the back and it helps settle them until they are able to pass wind.
Mine is the same. She’s mixed- breastfed and formula. My midwife said to use infacol if needed to help baby pass wind. Hope this helps x
My babies two weeks and currently going through the same thing! Does she stiffen up and go abit red when trying to pass wind? I’m contemplating changing my diet to accommodate but not sure how…
