Hedgehog - oh you poor thing, I can't believe this is still going on with your (not so D)H!
Do NOT get bullied into changing schools or home schooling, unless YOU believe it is better for all of you.
The reason your DH is at work, is because it is EASIER for him at work. It really, truly is. If you were to have all your children at home, with all of the additional needs that come with their disabilities, you would do yourself serious mental harm.
Spare uniform - most schools have second hand uniform sales. They are usually quite cheap. If the uniform is standard colours without logos, check online and see if you can buy it cheaper elsewhere. But DEFINITELY get extra kit. It's very expensive when you first start, but as they move through the school keep picking up odd items, here or there.
(What colours are they, anyway? Some MNers are bound to have old uniform in the right colours).
Car seats - I'm sorry, your DH has a point. I would never buy car seats that are very difficult to get in and out of cars. There are a lot of very good car seats out there, which are easier to get in and out of cars.
Brilliant that you're getting the alarm clock - I know you feel that's enabling him to get out of doing the few jobs you ask him to do, but the reality is that THIS job causes an absolute nightmare for you if its not done properly. You need to protect yourself from it.
Schedules - type up a schedule for all of your DC with all the tasks they need to do in the morning, and how long they have for each one. You're eldest DC are more than capable of doing some tasks on their own, and with some encouragement and help will be able to do more. Put large clocks in their room so they can see how they are going time wise
EG -
Get up - 7.10
Make bed - 5 mins - 7.15
Get dressed:
- pants, dress, socks, jumper, shoes - 10 mins - 7.25
Breakfast - 15 mins - 7.40
Brush teeth - 5 mins - 7.45
Check school bag - 5 mins - 7.50
etc, etc
You should also have a school bag list so they know what they need to take in every day.
You also need to have a timetable for the mornings - and if for any reason you have extra jobs that need to be done, you will know exactly where you will have wiggle room to fit them in.
I hate to say it, because I don't like them, but its lists, lists, lists all the way!!!!
