I have a no food rule. I have a celiac, an egg allergic child and two children with severe nut allergies it is just to much. I suggest parents bring small goody bags if they want to do something for their child birthday. I have also had parents donate books that we place the child picture with an inscription inside.
The child gets a birthday crown, made by me to wear and take home. We sing happy birthday at circle time and the child hands out the bags for the children to take home.
We always do parachute time as well as an activity selected by the birthday child as an extra fun birthday activity.
