SW,
The tweedles have little to no ability to focus. However, psychiatrist & I decided that trying to add a stimulant into the tweedles medications at this time was a time bomb. Simply wasn't worth it.
Instead, we had to work with school & the IEP process to address the attention issue there. The tweedles are in a day treatment program partially for that very reason.
Do the tweedles have ADHD? Most likely not - it's probably the PTSD, especially for kt.
A medication wash is a good idea though I wouldn't want to do it in the home setting. There are too many variables here. Can psychiatrist set up a hospitalization, do the medication wash & a complete evaluation?
Just something to consider.
