This seems okay to me. I mean my baby was also doing poo same way until he was solely on breast milk. Just don't go by poo color. Do you see other symptoms which makes you concerned like excessive crying, frequent poos etc. Still to be on safer side you should visit pediatrician.
That poop is normal. There's nothing wrong with your BM and confinement food. My baby had jaundice so he needed regular check up, i double checked with doctor on poop colour and it's all good. FM poop will be green, BM poop will be mustard/yellow.
