At my wits end with nearly 14 week old DD and her constant vomitting (call it what you like - possetting or spitting up doesn’t really seem to match the amount of liquid I get covered in), farting, explosive poops and constant burping are really getting to me. It’s such a silly thing to get so worked up over, but I really need to know when these sorts of things get better. I understand we all burp and poop; but when do their digestive systems mature enough to get better at all this?
