Where have the days gone?

Tonight I gave Madison a bath as usual, brought her downstairs to dress her, as usual and she kissed her daddy good night as usual. I then went to pick her up to take her back upstairs for bed. She told me know and went to the stairs. Aaron said "She doesn't need you to carry her up anymore." He was right. She climbed right up, went to her room and stood at the glider and waited for me to sit down. It has finally hit me... My little girl is growing up. How did it happen so quick?
