I was breastfeeding my bub from day 1 and hubby decided to supplement her with formula at Night so I can get some rest on day 4 as she was cluster feeding non stop and I was asleep when he fed her formula... the next day she has a few formula bottles in between when I rested as well and haven’t poop at all since.

Last poop was day 4 (2 diaper change- greenish poop). She has mild jaundice and now not pooping at all... should I be concern or have anyone experience something similar who can advice or etc?
