Yes you should make your 6 year old son wear diapers.
At 6 years old your son is still not able to hold his bladder too long and is prone to wetting his pants like other 6 year olds.
Having your 6 year old son wear diapers both day and night and all the time is a good thing.
You should also not allow your 6 year old son to use the toilet and make him use the diapers for both pee and poop.
Also don't allow him to change himself and instead you should change his diaper.
Some good diapers for a 6 year old boy are Pampers Baby Dry size 7, Pampers Cruisers size 7, Pampers Swaddlers size 8 and even Dollar General Gentle Steps size 7 diapers.
