I know that when I was in Missouri and my kids were young, we were part of the Head Start program. Due to my daughter's reactions to lot of of things and the struggles we had, it was suggested that I take a course titled "Parenting using the Love and Logic Principal". Head Start was sponsoring it, so I took it. The basic premise was: Instead of having an open ended question, ("Which sweater do you want to wear today?") provide 2 choices only, ("Do you want to wear your yellow or green sweater today?") This also helped when it came time to have daughter clean her room. She could not understand multiple step or open ended statements like "Clean your room". We had to make up a check-off list for her. It would go like this:
1. Put all dirty clothes into the hamper.
2. Put all baby dolls onto their shelf.
3. Put all Barbie dolls into the box under your bed.
4. Put all baby clothes into the dresser in the closet.
5. Put all of Barbie's clothes into the box under the bed.
6. Put all Lego's into the box for them.
7. Pull up your sheet and comforter and cover your pillow like Mommy does.
8. Set Cathy on your bed so she can rest. (Cathy was her teddy bear).
We had something like 20 different steps to have a clean room. Once a week she had the 20 step list for the top to bottom cleaning and daily she had the 12 step list for the general clean-up before evening games.
Granted, she had other learning and comprehension issues, but this, she got and could do. She still, at 17, needs a list of what to do so she can check it off. We are very big on plastic page protectors and dry erase markers in my house.
