OK. How does this sound?
Yesterday we did a cat nap (30 minutes) and then he went to bed for the night 2 hours after waking from the catnap. The 2 times we've done the cat nap this week, he wouldn't go to sleep any earlier than 2 hours from waking. Does that seem about right?
The problem is that he is STILL waking about 5-30 minutes later! Last night he came fully awake, but it only took me about 10 minutes to get him back to sleep with shushing and a little walking (I know, AP, but I had just come home from an outpatient surgery and really didn't want to be at the pat/shush or PU/PD for very long as I was still exhausted from being under General Anesthesia!). anyway, I can't figure out why he's doing this wake-up thing! He never used to, before about 3 weeks ago. Someone on the naps board suggested maybe TOO much daytime sleep, but I know yesterday that wasn't the case as he only had 2.5 hours of daytime sleep (daddy was in charge, and had difficulty extending his PM nap from 30 minutes).
So, what could be the cause? I will say that after I got him to sleep again, he stayed asleep the rest of the night, took a great dream feed, and then slept fantastic until about 4:45 when he started squealing a bit. But that was it! It was one of the best night's we've seen in awhile. But I really would like to eliminate the waking within 30 minutes of putting him down for the night. He NEVER used to do that - in fact, right after bedtime used to be guaranteed quiet time for DH & I, and now we never know what to expect!
Thanks again for all your help. I feel like we are finally getting on the right track! Today he had 1.5 hour am nap and a 2 hour PM nap, and then we'll be doing a 30 minute cat nap. I'll see if his night sleep is significantly different, I guess, with more day time sleep.
