Help! My son (almost 6 months old) only naps for 40-45 minutes at a time. Sometimes he wakes up happy sometimes still cranky. I try waiting to go in to see if he gos back to sleep and he doesn't. Although today for the first time ever I went in and held him a second and put him back down and after 20 minutes of mild fussing, he did go back to sleep so yay! I don't want to have to do that every time. Defeats the long nap if I have to go in there in the middle. He's pretty good sleeper at night and goes down for naps pretty well now that we have a routine.
