"I'm so incredibly proud of the woman you have grown up to be and I know that you are going to be the best mom to your new baby girl! Our girls are two weeks apart and I can’t wait for them to be besties! I am so proud that you do what you want to do and live your life the way you want, you will pass down all of those amazing qualities to your baby girl. You were made to be a mom! I love you!"
