Well, our kids are still very young so we only have "us time" when they're asleep, in bed. But even then we do lock, just in case our toddler wakes up and tries to come in bed with us (which happens several times a week). And then once we've had our alone time we unlock the door so that way he's welcome to come in and crawl in bed with us in the wee hours of the night. I don't think we'll ever stop locking the door.
