Naps

Why does a nap make my two and a half year old not sleep at night? Savannah took naps up until she was over four. And she would still go to bed good at night. But not Myra. Unless the nap was before noon, and less than an hour, Myra will not o to sleep until after 10... And the later in the afternoon the nap, the later the bed time :( Myra's nap today was WAY late. In fact it was so late that I debated just hoping for her to stay a sleep for the night... That didn't work out for us though, and now Josh is up with a wired two year old (thanks babe)! Man I wish I could take a nap!
