I do sometimes help Evangeline, but only in a very limited way - if she "freezes", I touch her arm or foot and then tell her where she has to put it next, and I'm always ready to spot her (or Ana) if she's doing something difficult.

The playground I love has a merry-go-round like you describe, but with bikes to pedal. It's really great.

What I miss, though, are real two person see-saws. Those are hard to find now!
