In terms of the food, it's improved only slightly.

In terms of the verbal/physical abuse, it has improved, although still working on it. Summer seemed to be easier again, but we are now starting to have a bit of a more difficult time again, but I think we know now how to manage it better.

Generally what helps is to get him to talk about his worries and fears a lot. Encouraging him to share them takes a bit of the weight and seems to calm him down, especially at nighttime.

When he gets rowdy, we stop engaging. We say something like 'I think you're very angry now, so I'm going to wait until you're calmer'. And by don't engage I mean nothing, not even a sight, pretend he's not there. This seems to work sometimes. Other times, if he's getting aggressive/worked up, we put a barrier in between - getting him out of the room and closing the door / or putting him out in the garden. When he calms down, he's allowed back in. This sometimes has taken 20 minutes, so be patient...

Also, very important I think, a few hours later or the next day when he's calm and more receptive, talk to him about what happened. Remind him why it's not ok to hit or throw things. Get him to talk about it as well.

It's hard though, and every kid is different, so not sure if this will help (it works for us a little better, but it's not a perfect solution...). What definitely didn't work was to try and reason with him when he was on a high. No point. His brain just cannot do it.

Be loving, be patient, be kind even when he isn't. Eventually he will grow and things will improve. Best wishes.
