The baby is almost three days old. He hasn't pooped or had a bowel movement in the last day. He only started producing milk today and ate well, with milk dripping down his cheeks. He also has many spit ups. But he still hasn't gone to the toilet. We feed him on demand, these requests come every 2-3 hours. The baby isn't crying, but he does have gas. Is this normal?
