On holiday with teen dd and 6 yr old ds. They are on sofa bed in living room, we hav a bed room . Both the door to patio and main door are openable from inside. I have a fear ds could wander while we sleep. Totally irrational as he never has. But it is first time abroad. I worry dd would not wake as she does not have parents spidey sense. I've blocked both doors with chairs but still worrying. Why can't we lock the doors from inside 😩😩
