Thank you so much for responding.
To extend his naps, I have tried w2s on several occasions. I would go in at the 30 minute mark or sit in his room and wait for the thirty minute mark to hit and gently move his arm. He would stir slightly. This worked on 2-3 occasions. However, most of the time he would start thumping his legs which brings him right out of his sleep cycle. I have also tried to hold through the 40 min. jolts as he jolts a lot both for falling asleep and at the 20 and 40 minute marks. It is difficult b/c he sleeps with his hands above his head (this is how I know he is asleep) so I can put pressure on his hands and hold his legs but when he opens his eyes and sees me over the crib, he cries right away. I have also tried to let him resettle by leaving him for 20-30 minutes in the crib if he is happy or a little fussy. He seldom resettles himself. I always go in if he is crying. I have tried to help him resettle by putting my hand on his tummy or covering his eyes but have only had luck one time. Lately, I have not been trying to extend b/c I have had little success. Sometimes we will go for a walk right after he wakes to see if he will fall back asleep in the stroller - no such luck. Once to twice a week, he will extend his morning nap on his own. I think that he survives the jolts and leg thumping and can get back to sleep on his own. When he does extend, his naps are usually 1 hour 15 min. to 1 hour 45 min. This is very rare and never happens twice in one day.
He is cranky and fussy when he wakes from a short nap. When his naps go longer than one hour, he is like a different baby - so happy and cheerful.
I discovered yesterday that 2 hours+ is too much A time for him. I am making this assumption b/c his naps got very short (20 min -35 min.) This morning I put him down after 1 hour 40 min. A time and he went to sleep with little fuss - eyes closed after 5 min. We are twenty minutes in.
I keep reading that babies start to extend their naps on their own around 5-6 months but we haven't had much luck here. I am committed to helping him extend his naps as I know that he will be a happier baby. In fact, we stayed home all week to be really consistent and work on the naps. I wanted to watch his cues really carefully and avoid missing the sleep window. It wasn't any better than when we went out here and there the week before. I must say, I find his cues very difficult to read.
Another question, just wondering if the leg thumping is common when babies are falling asleep or coming out of a sleep cycle?
I really appreciate you help and time.
