Mom and Dad?

Sometime over the last month or so, Harmon started calling us “Mom” and “Dad” instead of “Mommy” and “Daddy.” It makes him sound SO grown up and it’s so odd to hear, especially since I still call my Mom “Mommy!” He’ll say things like “Where are we going, Mom and Dad?” or “I had a good day at school, Mom and Dad!” Almost any statement or question contains a reference to “Mom” and “Dad.” He’s growing up fast enough but his language makes him seem so much older!
