Yes you should make your 8 year old son wear diapers when camping.
Diapers are an awesome way to go potty when camping or at anytime.
When your 8 year old son is camping and wearing diapers there's no need for him to find a toilet or find somewhere to go potty.
Your 8 year old son can just potty in the diapers and it's also a great option when sleeping in a tent.
If your son needs to pee he can just pee and stay in the tent and go back to sleep.
I've slept out in a tent camping before wearing just a diaper, shirt and socks and it was awesome.
I then also got out of my tent in the morning and sat outside wearing just the diaper.
Having a campfire at night and sitting out in a diaper is also an awesome thing to do.
I would highly recommend you diaper yourself up as well as your 8 year old son when camping.
Camping in diapers is awesome.
Dress your 8 year old son like Tommy Diaper Boy below and let him play outside in the camp area with just his diaper and shirt.
