Hello I’m just wondering if my babies poop colour is normal or not as google hasn’t helped me at all. He was strictly breastfed until recently my supply dropped and I was requested to supplement with formula as he is losing weight, they suggest I put him into good start + liquid he’s only 3 months old he went from pooping his yellow orange colour to this very very dark green his tummy seems to be upset a lot now is the poop colour normal or should I switch formula idk what to do 🤦🏼‍♀️
