I know what I am about to say may cause controversy, but ... here goes.
Don't be afraid to use children's TV to help you organise your day.
My ds is having a difficult time at the moment as I am recently post-op (a hip thing) so fairly immobile, and husband is trying to continue earning an honest living, from home as much as possible.
We have identified which tv programs ds likes best (we steer him towards good stuff, he has never seen stuff like Power Rangers yet) and we are building our days at the moment around the TV schedule, fitting in other activities around it.
so at the moment ds sits in bed with me reading first thing in the morning, while dh makes our cup of tea. then, after we've all had a play in bed (under the duvet is our submarine), ds watches tikkabilla while dh helps me get dressed, and we get brekky ready.
After Brekky, dh tries to work, while I play with playdoh or scrapbook sticking or something, and try to persuade ds to dress himself. At 11:00 ds settles down to watch Balamory, fireman Sam and Bob The Builder. this gives three quarters of an hour to get on with something useful (currently me supervising dh sorting out a load for the washing machine, trying to empty the dishwasher myself - takes ages when you can only place 1 plate at a time in the cupboard)
Then we do whatever games I can manage, counting, building stuff with bricks, etc. until dh makes some lunch. then he takes ds to the park or play centre, so I can have a nap, or check out mumsnet or some such.
Some days there is something good on at 3:15, or I might have taped Numbertime or magic key for him to watch. otherwise we play and do things together until 6:00pm, when ds settles in for a session with the TV, which calms him down for bathtime.
It doesn't always go smoothly, but using the TV helps to strucgture the day.
