Great news, micoverde! Here LO is going down easily (I am told, am at work then) for his 1st nap after 4 hrs A time and even for his second at 3 hrs 15 A. Got him to sleep just before 7 pm. He definitely is bothered by teeth or something because he cried for 30-60 seconds or so at 1 and 3 somethings.
He woke at 4:30 am (ugh). He was crying and sitting up, seemed like he really just wanted to get more sleep. I gave him Tyenol and changed him, then fed him and got him back to sleep (had to put my hands on his back in the crib for about 4-5 minutes) around 5:05. He cried out about 10 minutes later but slept til just before 7. So he is slowly catching up on sleep, we hope!!
