this bites!

my 2.5 year old generally naps 12-3 (for a two hour block somewhere in there). she passed out at 2 (!!) thanks to a 15 minute noon car nap. she's still asleep.

she generally goes to bed at 7, even if she lays awake in there for a bit. do I wake her now and hope she isn't a beast? do i let her sleep but still put her down at 7 even if she reads or plays?
