Hey LMS & BEAN
Far be it for me to tell anyone to or not to medicate. IF I had it to do over again? I would not have put a single dose in his mouth. At 16 he finally refused medications for good, and his behavior is NO different than it was on them (he was right) = At 5 - look for a psychiatrist that does CBT (Cognitive behavior therapy) and get into it with him. Learn how to out-wit your kid on a psychological level. It will make you feel like super Mom - promise.
I say this after 11 years, and 64 medications.
I am NOT saying this for everyone - So don't throw Ritalin. I'm just saying he's 5 and I think CBT and play therapy would be a better starting place. Lets let his little liver grow up a little.
He is just a bean after all.
