My daughter was three when we bought our first home. One of the first things I did after the boxes were gone was install a shelf for glasses inside the entrance to the house (the entrance we use, not the front door). They still end up on the floor sometimes, but now she has a place just for them that is distinct from the clutter and mess in the rest of the house.

We have a shelf inside the back door just for my daughter’s glasses.
