I only have 2 and can barely keep it together! The second is thankfully more into toys and entertaining himself than the first, who still demands constant social interaction. But I can't even use the computer while the 15 month old is awake because he screams to get online. He doesn't have the touchpad down yet so I have to help him, and Starfall is driving me bonkers. I guess I should just view it as building endurance for the endless games of Candyland which are soon to come. I often wonder if I'm anemic or something because I'm exhausted by noon, but then I remember that I'm just old.
