Most of the adults you see at the various group things are stay-at-home moms. Most. Some stay-at-home dads. Some of the moms have part-time jobs. I don’t recall any dads with part-time jobs. But many dads are present while also working full-time. You get into a rhythm, have a schedule, etc. and you can work it out. My wife is fairly unusual in that she runs her own full-time business. Many moms don’t like her, presumably because they gave up their careers to do this and are jealous that she does both.
