In our family we do lots of Mommy dates and Daddy dates. We think it's really important for our girls to have one on one time with each of us. We both take this time to teach them special things we want them to know. We also teach them how they should be treated when they are on dates with boys someday FAR, FAR away! LOL! 
Sometimes we take them to do really special things. Sometimes we just hang out.
Things like getting a haircut or a trip to Target can be lots of fun!! Renting a movie, riding a bike or flying a kite are extra special when we really pay attention.
I love these memories. Some of my best moments with my girls happen during mommy dates.
