I’m in desperate help as I can’t burp my 9 day old. I have put her on my shoulder which does not work. I’ve also sat her on my lap and rotated her and also patted her back and that doesn’t work either and after a while she resists and throws her head back. If she doesn’t burp, she is in pain and discomfort. She also has vomited all her milk up twice because she wouldn’t burp and I worry when I’m asleep she will do that again. Any other tips or hacks I can try? Thank you ☺️
