You need to set age appropriate tasks that he needs to do to earn his pocket money.
you don’t say how old he is but he should be expected to , Keep his bedroom tidy ie, dirty clothes put in the hamper ( if you lack space get one that hangs on the back of the door) if he’s old enough he should be folding & putting away his laundry. Putting away his things. Vacuum once a week.
Setting & Clearing the dinner table, learning to load/unload the dish washer or helping with dishes.
( my youngest daughter started doing dishes, washing,drying putting away when she was 4, I came out to the kitchen one morning, she’d put 2 dining chairs together to stand on and, wearing my gloves, was washing bowls & plates after already doing the cups & glasses, I tried to take over but she was like “mum, I got this make yourself a coffee” so I hovered until she was done).
Making their bed, helping prepare & cook dinner ( fussy eaters are far more likely to eat it if they helped make it)
To vacuuming, mopping , taking out the trash & recycling Etc. ( most kids enjoy hoovering)
set “Special” tasks he can do if he wants to earn extra cash.
praise their efforts, don’t criticise. Never discourage them from Attempting a task, there are no gender roles with house hold chores, it’s People work, if you live there you need to contribute.
Its our job as parents to teach our kids to Do for themselves Not to do everything for them, far more often Daughters are taught these things from a very young age & Sons are not. We often do it our selves because it’s quicker & it prevents the child from achieving.
I can tell you now that Adults who have not learned to look after themselves , they move out of home & then get Flatmate/ partners who get fed up real fast with learned helplessness & weaponised incompetence.
