We are glad the real Nate is back. He's had an accumulated sleep deficit for about a month. We weren't sure for a while because he wasn't napping but his body was just in stress mode because he was overtired so he wasn't sleeping well (hey, just like us for the first year of Nate). I think he is back to normal now.... I sure hope anyway, it's been a challenge for us. I can tell he is much happier .
