Nope, never. Too many paedophiles use babysitting as a route to children, paedophiles are almost always male, therefore, I only use female babysitters.
I’ve personally known 3 male teachers who’ve been fired for inappropriate touching of female children (one’s now serving 15 years in prison for offences against children). Never had a problem with our female teachers.
I don’t rely on DBS checks - all that means is you haven’t been caught yet.
