Yes and like previous said if they go awhile without it's ok too. Just means they are using everything they are taking in and have no whaste, usually during a growthspurt. My son stopped going constantly at a couple months old.
Yes! Lol mine pooped every time she sneezed, coughed, blinked (that one is a slight exaggeration) lol but you get the point. We went through a hundred diapers or better a week for maybe 6 months?
