Explanation:
The possessive noun "childs'" indicates plural possession, meaning it indicates multiple children possessing one object. Usage of "a" before "childs'" makes it incorrect because "a" should be used before a singular possessive noun.
Edit: It should also be noted that "childs" is not a word. Plural possessive would be "children."
