My son is a mo and half and im wondering why he isn't pooping daily? he poops like every three days is this normal? and why is he so gassy?

With breast feeding: Even once a week is normal, if there is good weight gain and no unusual crying.

Constipation or norm: Breast fed kids may go a little every feed or one bulky stool every 7-10 days & if soft they are not constipated. Most formula babies go 1-2xd. Any stool that is dried out is constipation & a sign things are not moving along fast enough. Gas is from air swallowed or gas produced by gut germs.
