How many children do you have and what are their ages?
As a parent of 2, 15 and 13, this is a topic for sex ed class, 5th grade here, ages 10-11.
Prepubescent children would only be interested in this topic if some misguided adult fed them with bullshit.
Oh, and you said that the FL law was pointless since no educator would teach kids gender/sex ed K-3...
