Siblings of AD/HD child

I am a divorced dad with custody of our 6yr old boy. His 1/2 brother has ad/hd and is in BOCES at age 9yr. My ex states that our son has rage episodes with his adhd 1/2 brother but blames it on the stress of the divorce. She has had depression for years and states that when the two boys fight she just walks away. My question is: Is it possible that the rages our son is having,(only at his mom's house....not at school or anywhere else) could these rage episodes be caused by the frustration of dealing with his AD/HD older 1/2 brother?? Any thoughts would be greatly appreciated. <font color="orange"> </font> <font color="black"> </font>

as grown sibling of very hyperactive sibling I can say that it was very hard to handle my sibling's inability to control themself.

It wasn't within their capability at that time. Our household went through the diets, medications, alternatives, you name it it was probably tried. My folks weren't flakey either.

I resented the amount of time necessary to deal with my sibling. I wasn't as aware of it then when we were children but now I can honestly say it was hell. We are closer in age than your son and his half brother.

I don't have any thoughts as to how to help but just thought I'd weigh in as someone who grew up with the most hyper sibling around. Wasn't easy. Wasn't fun. Even with constant discipline in supportive single parent household (pa passed away) there were many, many rough times.

The rage could be a combination of things. One the change (divorce) the other is that an adhd child tends to take up alot of the parents attention, therefor the younger one may be feeling a little left out using rages as a way to get attention from mom. Mom needs to get a handle on the depression with use of meds (imo) and try to set time out specifically for the one throwing rages. In the mean time she needs to let him know she loves him and cares about it. A six year old isn't very well equipped to deal with adult emotions (stress, anxiety, anger, ect). Hopefully no one is badmouthing the other parent when the kids are present, this to can have an impact on the childs behavior. My ex used to bad mouth me all the time and lets just say I have had my hands full. (actually been kind of a nightmare) but awwww well life is just a movie right?
Maybe when the 6 yr old comes back home you can ask him how his visit went at moms and see if you can pinpoint a particular behavoir that is happening. (the impulsivity of the adhd child pulling 6 yr old strings)
Hard to truly say. I do know from experience about those I mentioned. (and still learning)

Burned out mom

good luck
