I have a 5 week old that has drastically changed feeding behaviour during this week. Wondering if this is normal. She didn't latch properly after birth and got jaundice. At the hospital we started giving her donated milk from a bottle. When we came home, I started pumping and supplementing with formula. After a while, she started crying in pain and we thought she was constipated since she didn't poop. So we switched formula and everything got better. She burped nicely when taking breaks and didn't spit up as much.
Since changing to the new formula, I've also tried to introduce more breastfeeding and giving less formula. We use liquid formula, and the containers were too big. We couldn't go through them fast enough and had to throw away the remaining formula. So we switched back to the first formula since their packaging was smaller.
We've been giving her this first formula again for about a week. Now she's not only spitting up more again, but also vomiting. I've also noticed that she's got spots on her face and scalp. I first thought it was infant acne, but now i think it could possibly be a reaction to the formula. She's got really difficult to burp and she's crying in pain every time we take a break when feeding. She's more comfortable when on the breast but she will also sometimes completely refuse it. Most symptoms indicate reflux and I've been more gentle with burning her and keeping her upright.
My question is, has anyone else experienced anything similar? Is this a phase? Is it a coincidence that she's more difficult now, or should I really blame the formula?
