It is extra nice to receive a gift when you know someone put time and personal effort in it. So upgrade your gift and make the birthday boy or girl happy with a happy birthday coloring page. Dad will certainly put it on the refrigerator! Our happy birthday coloring pages are a lot of fun. We have them with Happy Birthday in letters which you can use as a card, with birthday cakes and more. Some are easy some a bit more difficult (for adults to use). Turn your page into a birthday card by folding it in half and writing the birthday girl's or boy's name in big colorful letters. Add confetti dots in as many different colors as you can and a few balloons in their favorite color.
