It’s completely normal…as long as they aren’t distressed with it x
Both my boys are more like 10-14 days. Doctor not concerned as not hard when the poo finally happens
If you’re really worried about it or baby doesn’t seem themselves I’d see a GP but if not I’d say give it another couple days🩵
Breastfed babies can go up to 7 days with no poo. My youngest went 6 days with no poo then definitely made up for it on day 6 😅 the doctors said its normal but past 7 days they advise going to be checked and giving them either lactulose or suppositories to make them go and stimulating the bum to make them go by very gently rubbing a cotton wool bud round the bum hole as it can stimulate them to poo xx
