Question: how often should my 1 month old poop on formula?
Answer: Newborn babies who are breastfed may poo at each feed in the early weeks, then, after about 6 weeks, not have a poo for several days. Formula-fed babies may poo up to 5 times a day when newborn, but after a few months this can go down to once a day. It's also normal for babies to strain or even cry when doing a poo.
