she's 16 days and has had a runny nose and been spitting up from the mucus. I've been pretty good at keeping track of when she eats until yesterday when I just started letting her nurse even to use me as a paci because thats when she started having a runny nose and all that. I just feel like she wants to nurse for comfort and I was okay with that. So it's been about 3 hours since her last actual full feed but about an hour and a half since her last little snack. She's sleeping, should I wake her up or just let her sleep for a bit?
