spotty that's an awful feeling isn't it. I seem to have blank patches during the nights when I'm exhausted. Like last night, I remember putting Ethan in his Moses basket after the 11pm feed. Then I don't remember anything until I woke at 2.45 with him on me. I can't work out if he'd had a feed in between or if he'd woken around half 2, and I'd got him out and he settled for a cuddle before the feed!
thankfully he was in his sleeping bag, on my chest, on top of the duvet, so in a safe position at least! 
pidj I'm glad work went well and dp and ds survived. Hats off to you for going out for 4hrs though. I wobbled leaving Ethan for 1hr the other night for Zumba (it was the first time I'd been away from him). Although I remember finding leaving dd (dc1) a lot easier than I'm finding it now. Maybe it's this 'last baby syndrome'?
Well Ethan's lungs work, he just managed to make himself heard while I made breakfast for the big dcs and he was upstairs in bed, by shouting! No tears, not upset, just shouting for attention!
