Aw, this is such a sweet post. A. Grace is such a beautiful child. Ican understand your wanting to spend every waking moment with her.
As others have said, the time goes so quickly and soon they are their own little people and then off on their own and away from your mothering.
I remember kissing my Sarahs' hands all the time when she was a baby and then watching them change into beautiful musicians hands with lovely long fingers which she now uses to play the piano and express her emotions.
Treasure all these moments because you will want to look back on them often to sooth your heart when your babies begin leaving the nest. You've got plenty of time to store all this up in your heart now.
Kisses
