Mothers - What do you love the most about your daughter(s)?

i'm 17... and my daughter is 11 months old... i'm young, but i wouldn't change having her for the world.. she is adorable, and she is sweet in every way... your right, it is hard to pick one single thing, but if i had to i would probably pick the way she cuddles up with me and says "kissy mommy" and gives me a huge kiss on the cheek.
