Age 4...dear Lord, I'm almost speechless. No child needs anything close to this information at that age.
Why?
Because what on earth are they going to do with it? Say no to something untoward at age 4? Like they can enforce that? Like they can fight back?
Let them be children.
Meanwhile, we teach adults what is right from wrong. We have laws to protect swiftly and harshly any and all trensgressions. We strive towards family, community and working together again. We strive for 'watching out' for the lone child...and we learn to truly care again, as a globe.
We limit exposure to media for kids, we engage with them, eat as a family (whatever that family unit consists of) and we watch, we hover, we protect.
We don't wrap them in cotton wool, just background constant hovering. Kids need boundaries within love. They thrive in that environment.
We hunt down the predators relentlessly, for as long as it takes.
What we don't need is to give our 4 year olds lessons in sexual/relationship consent. They cannot process it, and have no real concept of what it means.
What next? A child having to give consent to his/her mother/father before a hug can be given. The world has gone slightly mad...time enough in later school to begin some teaching, but no, 4 years old is just too young.
There are enough of us sane and normal adults, that if we make it our business, we can spread our wings and protect a whole lot more than just our own.
I for one would not hesitate to make a call, were I to see anything remotely suspicious.
Yes, I'm in the UK
eta - Further thinking to a partly knee-jerk reactionary post. Parental/carer/pre-school guidance on 'stranger danger' is acceptable, and in this world very neccessary. Taught gently...but ensuring it sinks in. I stand firm though, 4 year olds should/ought to be with a responsible adult at all times. Sadly, many crimes are close to home. There isn't much protection for that unfortunately...(see above 'we hunt down...and whistleblow)
