I'm confused...I've been spending the past 2 weeks trying to figure out the cause of my baby's gassiness, congestion, and diaper rash...which the gassiness is only getting worse (no sleep last night.) And I'm wondering if it could be thrush. My nipples did crack a little bit a couple of weeks ago in the beginning when my milk came in and were sore, but that quickly went away once my baby figured out how to control my OALD. Now, my breasts feel fine, but I do notice that the roof of my baby's jouth is a little pearly. Does that definitely mean thrush?? And does this mean I need to go to the doctor or can I treat it myself? I'm already tired of going to the doctor for every little thing, but her gassiness just keeps getting worse.
