Yeah, I thought about that, too. In the books (which I know are completely different) Bellamy's mother never left their home, instead sent Bellamy to do all of the errands. I don't know how they got by if she wasn't working, though.

There were also those random searches in their rooms, though. The only possibility I can think of of them getting through that would just be if it was a new thing that started a few years after Octavia was already born and could hide in the floor. Or maybe their mother would fit in the floor (though I doubt it) and Bellamy would simply say she wasn't home.
