with parent supervision, esp in the bath, I have no problem with it. Jessi was about that age when Tyler was born and she diapered him quite well. Used a ton of wipes, and we never had her do the messy diapers, but she would BEG to change him, put his clothes on (that took FOREVER and sometimes he looked very uncoordinated, but so what? Neither of them minded!), feed him, read to him, etc... But I was ALWAYS near the action to supervise. For giving Tyler a bath, I didn't let them be alone, but I did let her get into the tub with him either in the baby tub and her in the reg tub with both of them filled with water or once he could sit up, he had a chair thingy to keep him from falling over and she would play with him. Both had fun and she helped wash his hair, etc.. By the time Tyler was 9 mos old, Jessi was better at keeping soap out of his eyes than husband was, lol!
But I knew families where 7 or8 year old kids gave baths alone, or cooked alone. Each family has its' own rules and patterns, but I would worry about drowning so I would supervise very closely in a bath.
In your son' case, he needs to put it out of his mind. There is NOTHING he can do about what his exwife sets for their son's chores. Worrying about it solves nothing.
