Insomnia?

Fell asleep with kids tonight(and last night) at 8:30pm.
Woke up when J came to bed at midnight.
Am still awake at 1:49am.

Same thing happened last night.

Why is sleep so messed up for us all?

So it's been a month since my last post about L's sleep lack-of-schedule.
I think we have pretty much transitioned to one nap a day, but still it varies each day....
Lately a nap after lunch ha been working but we still get a couple of days a week where he'll pass out sometime in the morning. Being out in the car tends to put him down. Example from this week:

Sat - asleep at 12:30 in the car seat, slept until i woke him at 2pm
Sun - lovely 1-3pm afternoon nap that I might have indulged in too:-)
Mon -asleep at 11:15 am, in car seat, eta 5mins from home! Slept until 1pm, in car seat which I brought into the genkan with him asleep in it!
Tues- out to it from 12:20pm after morning playdate. Asleep in stroller until
Wed- asleep at 9:30am, while in ergo doing shopping. Awake at 10 after unsuccessful attempt to move from back to car seat:(. Afternoon nap 2pm-3pm
Thurs- asleep 1-3pm, in stroller

Kinda random, right??I know the movement of vehicles sets him to sleep but still!!! At least Mon was the only day he fell asleep before I could get him lunch.

Wonder what tomorrow will bring? Am guessing that I will be needing an afternoon nap the way this is going-- wonder if I can get K on board??(altho napping her means super late bedtime at night ***so*** not worth it! Better off catnapping on lounge while she cuts/draws/watches tv ;-)
