It sounds like there are a few things that might work for you. One thing is to make sure you have the right setting on the game system and your router to make sure you have time limits set up. Let’s start with the game system. What game system does your child use? Secondly, what game is your child playing. Different games cause different issues with ending the game. They are designed that way. Some games don’t save your progress if you are in a game, some games are mission type games you play as a team and you are needed by team mates, others cause high levels of dopamine and make it extremely difficult to come down from playing and cause them to emotionally crash. What game is your child playing. Lastly, I think setting up more structure around game time is what might work for you. Set expectations in advance for days and times. Set up a 2 minute conversation before he plays to lock in the expectations of what he is to do after he plays the game. Sometimes if you sit with him at the end of his play time you can watch him and engage with him and the game so you are connecting about the game. This helps you both be ready for the dopamine drop. It can ease it until he has the skill to do it himself. This works by setting two timers. 10 min and 5 min warnings for both of you to start engaging. It is also good for your child to know what is next after playing. Something enjoyable like play outside, arts and crafts, or legos. Avoid chores and try not to tie snacking right after playing. I hope this helps.
