Start out by getting prepped first! Paint, brushes, paper, wet clean up cloths nearby and maybe even set up on top of newspapers on the floor if you want. Trust me, you don’t want to get your child’s foot covered in paint and then realize the paper is on the other side of the room!
When you are set start with one foot. Paint the bottom of the first foot with your child’s selected color of paint. Help him, or let him, stamp his foot on the paper. Clean the first foot off, and then paint the second foot. To make a heart have a child stamp the second foot on top of heel of their first footprint to create the pointed bottom of the heart and toes create the two rounded tops.
Your child can add more paint and decorations to their hearts if they would like.
