For girly girls, the world may revolve around makeup, nail polish and anything pink. You might think that related activities are reserved for mothers and daughters, but dads can also get in on the action. This will show your little girl that you don't take yourself too seriously and that you'll always make an effort to share in her interests.
Turn the bathroom into a spa for a day. Stop by the neighborhood drug store, pick up her favorite color of nail polish and paint her fingernails and toenails. Maybe mash up a couple of avocados for a homemade face mask and slice a cucumber to place on your eyelids. You could even find recipes online for homemade cosmetics. Then, if you're game, allow your daughter to give you a makeover. Nothing's funnier than seeing Dad wearing blue eye shadow and lipstick.
