Hi
I just bribe them with legos
Well for real what we have done in the past with our kids is as follows. Mind you we have a seperate building 480 sqft that is detached from the house. It was my "office" that had a shelving system all around it. Every shelf went from ground to celling . Then the floors were covered with train tracks, houses, building, cars, job sites you name it was going on. From the time our oldest was 5-ish he and his following brothers (each 2 years-ish apart, 3 of them) they have had access to it all at basically all times.
The super rare stuff was out but higher up. They had a stool and mini ladder to really get anything.
Now the catch was that they always had to clean up EVERYTHING. That meant in its place and all proper. The Playmobil and legos do not go out side in the dirt. Concrete is ok but in limited amounts. If they did not they did not get welcomed back until they did clean up. Then they could take more out .
The way I figured it was that if i showed them the respect, they would show the toys respect that I demanded. It worked very well but I do have a German wife to thank for her
magical powers.
I never worried about them swallowing parts & things as they really were not near me or the toys, all they did was follow the udder around.
At times things were all over the place but it was well worth listening to them play and interact with the toys and each other. I wish now I had a video going at all times.
