The standard for any child with
ADHD is a very regulated schedule and I think that this should also go
for bathroom visits. By the way, I am also the CL on the ADHD forum - http://www.medhelp.org/forums/ADD---ADHD/show/175 feel free to post any questions there too.
In term of this tantrums, etc. You might want to check out the book, called "Raising Lions", by Joe Newman. If you go to his web site and subscribe to his newsletter you can get $3.00 off the book.
