DS1 (who's 5 in 2 weeks) broke his leg at school - first day back, was only there 2hrs!) falling over a ball. He's broken his tibia and has a cast from toes to groin.
This cast I think will be on for 4 weeks, then a shorter cast for 2 weeks if all goes well.
I've just had DD (10 days old now) and had a bad tear with lots of stitches so advised not to do any heavy lifting (not sure for how long though).
DH can be at home next week thankfully then will really have to go back to work (and often works away Mon-Thurs).
DS2 has SN and has no clue about the baby or DS1's broken leg 
but will be at his SN sch most mornings, collected by bus in the morning & our p-t nanny/his carer will be picking him up at lunchtimes (can see current circs will increase his hours much earlier than planned, hey ho).
We can increase the Nanny's hours temporarily and she is a star but she can't be here first thing or overnight.
DS1 is refusing to try his crutches - though tbh I'm a bit about a 4/5yr old managing crutches (incl stairs!) so we have borrowed a wheelchair so he can get some fresh air. Though the physios at hosp seemed keen for him to manage the crutches before discharge, DH was fed up & DS1 was screaming so they gave up.
Oh and so far we've had 2 disturbed nights with DS1 sobbing, me crying & feeling awful, now DH has reread the instructions on the calpol & neurofen we've started a more rigid pain relief routine
