When tidying up, does {child_name} put things that go together in the same place — blocks in one box, soft toys in another?

Follow-up: Does {he_she} sort by type on {his_her} own, or mostly when you ask?

Not yet
Puts things away randomly, or doesn't help tidy
Emerging
Matches one or two obvious things with a prompt
Developing
Sorts familiar items into groups when asked
Secure
Notices groupings and sorts things spontaneously

A simple sorting game — animals in one bowl, fruits in another — is a lovely next step.
