At the ripe old age of 2.5-2.75 we still mess with A times to get a good nap. For us we almost always have had a good hour longer in the eve than the morn. Mostly his choice. I pretty much put him down the same time every night and usually he will fall asleep at about 1 hour longer awake time in the eve than in the am. Unless he is sick, then you never know.
For example yesterday napped after 5.5 hours awake time but at bed fell asleep at 6.5 awake time. Unfortunately if it takes till 6.5 A for nap we are in for a very late night = early morning and an early day the next.
Talking it over with Dh we just don't think that even though PJ has his fair share of 30min naps, and he is taking longer and longer to fall asleep for nap it is still worth the effort to give get him a nap. If he naps he will stay stay awake until around 8pm at night - even if the nap is only 45 min. But no nap he can't last much past 6:15. To me that means he needs that nap --- even if it is a power nap.
I think in the past several months he has also started to regulate his night time sleep to be 11 hours so that is good enough that even if he does a 20 min nap he can make it to 7pm and it isn't so much that he might take a 1.5 nap depending on how he is feeling that day.
So in the end, even though we did have a few rough weeks with him fighting nap, I am not sure he is dropping it OR I am going to stop it b/c it isn't worth the fight. He will get used to the idea again in time. today it only took 20 min to fall asleep for nap.
now I need some serious help on how to get his mind to turn off at bedtime. You should hear him in there reviewing his day, talking about things that happened 2 weeks ago, counting, abc's, singing Thomas, pretending to be a race car.... crashing!! It is enough to drive me batty! Just go to sleep already!!!!
