P.R.
I am just asking a question, okay? Have you ever been overtired and not been able to go to sleep? It happens to everyone. I noticed when my children were little the nap schedule changed a lot and at various ages. My first child would get up, have breakfast, play for about an hour and then go down for a two hour nap, repeat the schedule, repeat the schedule and then when we fed her at about 8:30 she was raring to go until about 2 or 3 in the morning. This was a tough schedule for us to break with her. We had to do it by getting her up from her naps earlier, making her stay awake longer and putting up with the overtired stuff for a couple of weeks until we could get it around to a much more reasonable schedule. My second child would get up at 5 A.m. eat, play for half and hour and then sleep until 8 A.m. and then have a meal and play for an hour or so before the next nap. He was easier because by 10 he was down for the night until 5ish the next morning. The third one we raised was getting him up at 6 feed him and then dress him etc., because I had to drop him at the sitters by 7:30 to get to work by 8. Sometimes he was awake when I picked him up at about 5:30 sometimes we had to get him up but I didn't let him nap after supper until it was bedtime at about 9 and he rarely woke up during the night so I guess I was lucky.
None of my children napped in the morning after they were one. All of them cut back on the length of their naps (even the two or three a day ones) before they were 6 months old. I don't remember anything longer than a two hour nap after that and then it was once a day. If they were really tired they went down earlier at night.
Good Luck
