Sleepless Nights

So, Buddy left on July 1st for California. Perrin has been having a hard time sleeping at night. See, Buddy normally puts him to sleep. Buddy also takes care of Perrin until about 4:00am as well. If Perrin gets up during that time, Buddy rocks him back to sleep. The first couple of nights, Perrin sat up in bed at about 4:00am and demanded "Daddy!" Bottom line, neither Perrin nor myself are getting much sleep. I think the sleepless nights are starting to get to him because I found him like this today - twice.
