I'm now a 2nd grade Brownie Leader but was the asst leader for my DD's Daisy Troop. It is actually a pretty easy year - no cookies to sell, no magazines to sell (not allowed to sell anything

) which is great for getting used to Girl Scouts. You need to have at least 2 leaders and can set up a troop commitee - my troop committee consists of a Refreshemnt Coordinator (SNACK MOM), Trip Coordinator (I plan the trips, she figures out the details like getting money from the moms, permission slips, transportantion, etc), a Group Photographer (takes photos at all trips) and a Treasurer(this was key for me because I always forget to pay myself back and she doesn't)
We meet every other week for 90 min but you can meet for only an hour as Daisy's if you prefer. They earn petals which are much less planning than the Brownie's TryIt's and you can do as much extra stuff as you feel like.
If you want more info, feel free to PM me.
