How Big is Jackson?

SOOOO big! He is only three and a half weeks old, but already I can tell that he is growing like a weed. Nick and I both noticed that he seemed bigger last Monday, and he has only continued to grow and change since then. He is way too long for newborn clothes and has graduated to size one diapers. How I wish I could slow things down. I love that he is getting big and strong, but my heart breaks at the thought of my tiny baby growing up so quickly.
