First night home - HELP!

We are seeing our peditrian in 5 hours, but that feels like a lifetime right now. We came home from the hospital yesterday and breastfeeding had been challenging but seemed to be getting there.

But then he had zero poppy diapers yesterday. We called the pediatrician last night at 8 and they said we could supplement with 1 ounce of formula if we were worried he wasn’t eating enough. So we did. That was 10 hours ago and he has refused my breast at every attempt since then. Any advice?

On top of that, he literally will not go to sleep unless held - although in the hospital he did this just fine. I’m wondering if it’s the formula we tried?
