If hubby says a 6 year old child is big enough to stay at home by himself anyway he knows what to do, is he correct or wrong?

No right, no wrong. Depending how sensible & independent of your child.

6 years old might be a little bit too young. better to be safe than sorry!

No way as 6 year old child still needs an adult’s supervision at home.

too young even we as a parents have so much confident. for me is no no

I don't agree. 6 years old is sti too young to stay home by himself.

I feel that's still too young. Maybe slightly older like 8 to 10?

6 years old is still too young. Maybe a little older, say 8-10??

I won’t take the risk. He will still need to be supervised.

I feel that 6 years old is still young to stay home alone.

it depends. mine goes to and fro school on his own.
