First I want to say WAY TO GO MOM! You Rock J.! What a blessing for you to be able to be a SAHM! You are so right about them growing up way to fast!
As for nap time, well, there are some children who do stop napping around that age. So it's not that he would be abnormal if he did stop. However, if you are noticing that he is tired, he must still need a nap but for what ever reason isnt able to wind down enough to fall asleep.
Have you tried soft music, a book on cd or maybe a baby video to get him to slow down a bit to fall asleep? I read a book once where the dad (who was working outside the home) would record a special message for each of his 8 children on tape. The children would play their 30min tape each day during nap/rest time. All of the older children would rest for 1 hr and then back to school work (homeschooled) and the little ones would sleep for 1&1/2 hrs.
I have even gone into their room and rubbed their arms and legs and told them that it's time to go to sleep. And helped them settled down. Their little minds are going 90mph and sometimes they have a hard time slowing down to rest.
We still have a rest time during our day for an hour. Its a time for me to regroup and get ready for the second half of my day. And the boys, once the big ones realized it wasn't an option but a requirement, have settled into this routine very nicely. The 2 yr old still whines and fusses every day but that's not unusual for a 2 yr old. LOL
Good Luck to you!
Take Care,
