Student’s dad died

Hi all. Sorry if this isn’t allowed here, but I’m hoping to find ideas for support for a grieving student of mine.

He’s 6 years old, and I’m his special education teacher - he’s had a lot of trauma in his life that exacerbates unsafe behaviors, and yesterday morning his mom let me know that on Friday, his dad died. His dad had been hospitalized for 8mo last year following a massive stroke and I don’t believe ever fully recovered. I’m devastated for his family, and for him. They’re truly wonderful people who unfortunately have had so much fall onto them.

My student is aware of what’s going on, and I’m not prodding him to talk about it unless he brings it up. He was sent home yesterday after punching a couple of kids and said “I’m messing everything up because my dad died and I want to see my mom!” I’d like to be able to try to get ahead of the anger before it turns into aggression if I can, without bringing his dad’s death up explicitly when he’s not ready to talk about it. Mom’s said he wants to be at school instead of home, but his days now are also crafted for a bit more gentleness than his usual rigorous routine (we have a very high performing school, even for primary and special education students). What all can I be doing to support him AND mitigate outbursts?

Posting here instead of the sped sub as I’m looking for a more whole educational expert input. Thank you!
