Newborn feeding HELP :(

Hayley • US Army soldier & mother

My baby is currently 3 days old. She isn’t nursing for more than 5 minutes at a time every couple of hours. Even when she’s inconsolable she will only nurse for like 2 minutes. Am I doing something wrong?? I’ve tried burping, skin to skin nursing, different positions..I’m just lost and feeling like a bad mom because she has to be hungry right? (When we left the hospital she was 5lbs 6oz). I could really use some advice :(
