Anyone experiencing grey-green baby poop? My little one is on hypoallergenic Formula Milk. PD said it's due to the formula milk so it's normal but I'm still feeling sceptical about it.

Q&A from Nestle Website: 7. I am using the NAN H.A. Gold formula for my baby and his/her stools are dark green and very smelly, is there something wrong? A baby’s stool can be affected by a number of factors including the transitioning between different feeding options (example: breast milk to formula or between formulas).They may range from soft and unformed, yellowish mustard for breastfed babies to green for H.A. formula fed babies to bulkier, brown stools for intact formula (non H.A) fed babies.
