ftm concerned about 1 week old

Brianna

So my son is 11 days old and I believe he might have thrush I plan on calling his Dr first thing in the morning to see if I can get him an appointment sooner than our current scheduled one, my concer right now is that he has been acting weird while eating since this morning he only eats little bits at a time and right now it has been 2 hrs since he last ate and he should be getting hungry and he keeps rooting around but refuses to eat should I call his drs after hours number or will he be okay till tomorrow morning? I currently bottle and breast feed due to complications with latch when he was first born so we are transitioning into breast feeding currently I have tried both bottle and breast
