AQ, I finally decided, yet again, not to pursue the diagnosis. We did get ds1 into a really good group OT program once a week. They work on the upper body coordination that he needs as well as social skills.
Dh is getting me down more than anything atm. Lots of passive aggressive stuff and grumbling about, well, practically everything it seems. I think a lot of it is due to his chronic poor health but it's like a constant slow energy drain.
Re: tantrums - one OT expressed it particularly well about ds1. She said it's like when you hold it together all day at work and then come home and yell at your spouse because you had a stressful day. Same thing with kids and school, hence they are model students and then little terrors afterwards.
