I had to laugh about the no sleep. DS2 is happy and active, so apparently he's getting enough sleep, but DH and I are definitely not (I hoping for more zzzz after he finishes getting his molars).

When I'm around other toddlers at playgroup or in the park, I find myself explaining things to them like I do to my son, but I get a lot of blank stares back. I can almost see their eyes glaze over from Too Much Detail. I think I even scared one little guy. DS2 doesn't understand why they won't play with him, but when we're around slightly older kids (3-4) he gets really shy.
