A little Exhausting

Lately Jacob has decided that naptime is unimportant so he has been knocking his naptime down to about 30-45 minutes a day. This started about 2 weeks ago and I don't see any light at the end of this tunnel! No naptime? How am I going to get through the day with no naptime? My other 2 at least waited until they were 2 to give it up. I have tried pretty much anything I can think of to extend it too..from being really quiet to trying different times of the day and even letting him take 30 minutes and then seeing if he will take another short one later in the day. He has also decided to make his bedtime later than it used to be, although I will admit that he used to go to bed pretty early (6:30) and waking up earlier. It is making for a really loooong day and I was wondering why I was so tired all the time....Gee, I wonder?
