The firefighters in my city during the Christmas time will dress up like Santa and make visits to the local kids to drop off a toy when a parents signs up their kids. Well this year, my daughters happened to be outside when they stopped at our neighbor's house (I forgot that they did this) and my kids ran up to them, so they gave them a couple of toys and let them have their little visit with Santa even though I hadnt signed them up. I want to thank them for that by baking them cookies, but how many dozen do you think I will need to cover all the shifts? 4 dozen of 4 different types of cookies or like 5 dozen given they are firemen so will have a hearty appetite?? or brownies?
