When A Muggle Born Child Does Weird Wizarding Things, There Parents Have No Idea.

There Should Be A Wizard/Witch Who Works At A 'Mental Hospital' In London Where A Muggle Would Take Their Kid.

Then They Can Assure Them Things Like. "This Is Normal" "You'll See In Time." "She's Perfectly Ok." "Teach Her To Control Her Emotions" "Yer' A Wizard Child"

That Be Alot Easier!
