B.C.
'Watch and see how it all works' is a learning style.
My son is this way.
The first quarter of every school year the teachers tell me they'd like him to participate more, and then the rest of the year they have a hard time getting him to shut up.
He has to observe how everything works before he'll jump in.
He's a perfectionist and doesn't like to make mistakes - even if he is learning something new.
His standards for himself are higher than I'd ever put on him.
Just have her in one activity at a time and let her take it at her own pace.
Many 4 year old s act exactly as she did on the soccer field - it's not just her.
Team sports are hard for everyone to pick up, so hold off on those till she's older (7 or 8).
Work with her learning style and things will come along a bit easier than trying to go against it.
