Hello, this is my first time posting and I've gotten so much help from all of you out there--so, thank you! I'm working on extending my son's short naps (30-45) minutes. He's 4 months next week and been on EASY for about month, but I've had no luck consistently extending naps (despite trying all the ideas posted out here). So while I continue to work on extending his naps (and moving him to a 4-hour routine), what do I do when he wakes early and is content to play in his crib? Sometimes I can catch it and use the pacifier or shush/pat to get him to sleep longer, but other times, he just wakes and has no interest in falling back asleep. If he cries, I do PU/PD, but when he's happy which is most of the time, what do I do? Get him up? Leave him and hope he'll go back to sleep (although he never does)? And when do I put him down for his next nap? I usually stet our wind down after an hour and 10 minutes to get him asleep 1.5 hours after waking. But if he wakes early, and doesn't go back to sleep, he gets completely off the 3 hour routine. Does is sound like he's ready for a 4 hour routine? This is driving me crazy! Help!!
