So my boy is 2 weeks old today, he's a pretty calm baby never really cries, the pass two nights he hasn't stop making weird noises like he's having a hard time pooping, he's pooing like 3 times he's also now spitting up like 3 times after every bottle (breastfeed) I'm having a hard time burping him and he just seems very uncomfortable, he doesn't really cry but he can't even sleep deeply like he usually does, what can this be?
