The weekend before last Ada started walking unassisted.
On Wednesday I picked her up from creche. They noted she had been walking, and were amused that she applauded herself when she succeeded at it. They were amused and delighted - as was I - that when another non-walker gave it a go, she applauded him, too.
This weekend she was starting to yell “run, run” and accelerate around the house for her own entertainment.
