Kiddo doesn't want to sleep :(

We've been doing early bedtimes for two weeks and it has been going well.  The last two nights he's woken up shortly after being put down.  Tonight he had NO interest in going down on the first go, so I let him stay up, nursed him again and tried to put him down.  He seemed to go, but lo and behold, he's up AGAIN.  Thank goodness DH is here now cause I'm tired.
