Why do they have to grow up so fast?!?

I can't believe that my baby is 9 months old today! I hate that she is growing up so fast but yet I love to see her accomplish her little milestones. The crazy thing is, I have another army crawler. What is with my kids and army crawling? She is such a blessing to our family. She was so worth it!!! Both of my girls are! I'd go through the pain of infertility again in a second, knowing the blessings that came from it. I am so thankful for my 2 little miracles.
