By now you have learned that there are more things to do than petals, with the 2 yr Daisy program. Also, there are patch programs from other sources if you want to play with these---go to Scoutingweb and click on Traditions for a couple of lists. There is also a company called Patchworkdesigns.com which writes up patch programs for anyone, not just Scouts, and of course they sell patches to go with them---beautifully embroidered patches---and your troop can have some fun with these.
The GSUSA answer to your ques would be you ahould do one of the Journeys that are aimed at Daisies. Which is fine but you can't get an entire year out of a Journey book. So look for some other things. I say, find some small service projects that first graders can do -- go caroling at the nursing home, make some decorated placemats to give them, or to the VA hospital, etc---make some decorations to hand out when you go caroling (they can be snowflakes if you have people touchy about "holiday")--- our Daisy troop did that and the residents of the home were thrilled to pieces at the snowflakes (we made six sided star snowflakes and what a coincidence, we painted them blue & white -- covered all the interfaith bases and the residents could not have cared less what we did; we thought of them was what mattered). Our D troop did a food drive --- canned goods from home and some neighbors, and we "delivered" them to the church food pantry, each girl carrying a loaded bag (we met in a church that was kind enough to lend us their space, even though none of us belonged to their congregation & half of us were not even Christians).
The two big things you want them to internalize are service to others and taking on more responsibility -- so do things where they share chores, plan an event together, like a day in the woods (who makes snack, who cleans up), execute it and so on. You don't need a petal book to do that!
