Jill & Jessa Duggar -- We Had Locked Bedrooms After Molestation ... Our Parents DID Protect Us (VIDEO)

Two of Josh Duggar's younger sisters came out swinging for him, and for their parents -- saying they took several steps to protect the girls in the family after Josh confessed to molesting them.

Jill and Jessa told FOX News' Megyn Kelly their parents put locks on the girls' bedroom doors and on the boys' rooms. Jill said play time had to change too, so Josh couldn't be alone with any of the girls -- "My parents said, okay, we're not going to do this hide and seek thing where two people go off and hide together."

The sisters tried to put the best face possible on the situation -- much like Jim Bob & Michelle Duggar did -- speaking frequently about forgiving Josh, and the family handling this on its own. But watch the clip ... it's clear their childhoods changed drastically in the wake of the molestations.

Jessa pointed a finger at the legal system and cops in their hometown -- just as her parents did -- but TMZ broke the story ... authorities followed the law.
