There's a group called Daisies which is for late 4 year olds, 5 year olds, and early 6 year olds. My daughter is currently a Daisy- she's 5 1/2.
The Daisy uniform is soooo cute! It's a turquoise apron and they earn 10 daisy petals by doing different activities. They don't sell cookies until they're a Brownie.
Brownies would be for late 5 year olds, 6 year olds, and early 7 year olds.
They sell cookies and they earn patches by trying new things and helping the community.
I think the ages are within 3-6 months:
Daiy age (5) and Brownie age (6).
I hope that helps!
