Baby cries every time she eats 😭

My daughter is 10 weeks old . I was breastfeeding her but due to the frustration of her always crying, excruciating pain every time my boobs let down, and my really busy schedule , I chose to stop. I told the doctor and she said that maybe she had a milk intolerance. Well I’ve switched her to Enfamil Gentlease (while giving her some breastmilk during the day) and now it’s happening again. She has trouble passing bowel movements, cries every time she eats, spits up every time she eats, and is constantly fussy.

I added a picture of her on her best happy days ♥️ I hate seeing her cry so much😭
