siblings help and behavior therapy

[Guest guest]

Have any other parents here had any change in their child's behavior as a result

of therapy? My son's behavior is so out of control. He's 4 1/2 and has a 2 1/2

yr old sister and is teaching her so many bad behaviors. I don't know what to

do. He has an uncontrollable need to always make noises or use offensive words

" potty talk " and she mimics everything he says and does. I feel like I'm about

to loose my mind. This is so hard.
