Whew! That went by fast!

When you have a new baby, you long for them to utter "Mama" and "Dada" for the very first time.  It just melts your heart.  Well, those days are fading in our house.  Gray no longer calls us "Mommy and Daddy"  Instead it's just mom and dad.  It makes him seem so much older!  Doesn't four seem young to not say Mommy and Daddy anymore??
