Red/orange in urine diaper

Holly

My baby is just 2 days old, uncircumcised so it's not blood from that procedure. Is this normal?? I read first few days of life the urine is concentrated and you can see a rusty color in urine due to that, but every mom friend I have said they have never seen it with theirs. Babies first pediatrician appt is tomorrow but I'm wondering if I should take him to emergency?
