We find what we are looking for:

“There aren’t very many toys in the prehistoric archaelogical record. For a long time, archaelogists thought that was because prehistoric kids were somehow fundamentally different from modern kids. But now some scholars think that the toys are missing from the record simply because early archaeologists didn’t recognize them. Whenever they saw objects that could easily be used for children’s play, they categorized them as items used for ritual instead.”
