Girls, who have children of our age, or slightly older, how much do your babies sleep? Mine has been sleeping constantly for a week now. It's awake in general for about 3 hours during the day, the rest of the time it sleeps. Now I'm thinking, maybe this is not normal?! I used to sleep, but not as often, could stay awake all day and not fuss. Eats well, pees too.
