My 10.5 month old son has never been a great sleeper, we have always had problems with short naps and early wakings. It seemed like he was finally figuring it out around 7 months, and would take great naps and sleep 11 hours at night. At eight months he refused the cat nap, and we've been having lots of problems since. He struggled with A times of 3 hours since he was always OT, he just had too long of A time in the afternoon. I kept trying stretch out his A times in the morning and between naps one and two so we didn't have such a long A time in the afternoon, but this just led to short naps. We tried early bedtimes, but they don't seem to help since it guaranteed an early waking (4 am). He would usually have a few night wakings, probably due to being overtired. Basically, I was unable to stretch out his A times because he was always so tired and always waking early. We have a 7:15 bedtime and most days he is up at 5 or 5:30.
Last week I decided to try set nap times since nothing else seemed to be working. The first nap is at 9:15 and the second at 1:45. The first few days he had short naps and was OT, but then he had a few days when he would take 2.5 hr morning naps and an 1.25 hr afternoon nap, and then sleep about 10.5 hrs at night. It seemed things were getting better. Since then he has been taking shorter naps. Usually he will sleep 1 hr 15 min to 1.5 hrs in the morning, but I cannot get him to sleep more than 45 minutes to an hour in the afternoon and is so cranky when he wakes. He is still waking early, usually it is 5:15 am with a few night wakings. The night wakings are usually within 3 hrs of bedtime or at 3 am, and usually I can get him resettled and back to sleep within 5 to 10 minutes. FYI, we are also dealing with a couple of other issues-- somehow he forgot how to suck his thumb and now has trouble soothing himself, and there are some separation anxiety issues. I have to stay in the room until he's asleep, sometimes he needs shush/pat or a hand on the back, other times I just need to stand by his crib. Before he would fall asleep independently without anyone in the room.
Any advice on what I should do with the set naps? Does the morning nap need to be moved back a little to help with the early wakings? Or does it take longer for him to get settled into a set nap routine (its been about 10 days.)
