Dating at 10!
It in my opinion should not even be a consideration.
As far as a crush, that happens.....best is to keep it as friends.
Children are not being children for long enough.
They see boy-girl on t.v...and think it is something for maybe even them.
It is best to allow your child to remain as far from that until at least another 6-7-8 years.Even then, it should be watched, carefully.
