What Am I Doing?

So my little fella has been having a hard time sleeping the past couple of nights. I really thought we were past this. I mean for the four nights prior, he'd been doing a fabulous time with sleeping and had been doing much better with napping during the day- but I guess those days are no more. The problem that I have- besides him not getting enough sleep- is that I am not sleeping enough. I go to bed late because I choose to stay up and play on the computer or watch tv or whatever... and then when I'm ready to go to bed, I'm in bed for a few minutes it seems and then he's up. The other night, he was up for an hour each two different times. Last night, I don't even remember how many times he got up. I don't know why I just don't go to sleep once he's finally sleeping (It took almost an hour for him to get to sleep tonight and two hours last night- with rocking, bouncing, singing, putting him in his crib, picking him back up and doing it all over again until finally, he could be placed in his crib without screaming and could quietly be patted and sung to, then just being sung to, then nothing). Anyway, he's already been up once tonight and back down and he'll probably actually be up in another 30-60 minutes... and I still haven't even gone to bed yet. Part of me doesn't want to go to bed because I know he'll be up soon, but part of me knows that I should probably strive to get all the rest I can manage. Blech!
