Girls, what could it be? Tiny girl hasn't cried for four days straight, her chest is eating in small gulps and throwing up, she cries. There doesn't seem to be a runny nose, but she hiccups occasionally, snot is pouring into her hand like a river. Is it maybe from the bedsheet or teeth poking out? We're waiting for the doctor so she can take a look. Has anyone had water running from their nose with tooth pain?
