I know it's best to start early but when did you think your LO "got it"? If that makes sense. I clean up and sort of restrict where the toys are and certain toys sort of stay in certain rooms and we rotate through them throughout the day. He's only 11 months so I don't feel like he knows how to pull toys out; I've heard that when he does is when to teach to put them back. When is/was that for you LO?
