You can put tattoos in the eggs, you can also put in little cards with a # on them & the # matches up to a bigger gift, say a dollar toy, box of crayons, coloring book, lip gloss, ball, etc.. you get the idea. A for limiting eggs, just let everyone know that the Easter bunny said each kid has to find __ # of eggs and once they find them, then they can begin to open them. hope this helps you & have fun!
