So stoked for you. In my experience, there's nothing more incredible than the birth of your first baby. Nothing can prepare you for that moment of meeting them for the first time.
Last weekend was my 13 year old's dance recital, and she had her first ballet solo en pointe. I knew that I'd get teary during her dance, but wasn't prepared to fall apart so thoroughly afterwards. I went to congratulate her and tell her how proud I was, but instead what came out was, "you were only five pounds and the first thing that I said to you was, 'oh, I know who you are', but I guess that I didn't". Then I started full on ugly crying and couldn't stop. I don't even know what I meant by my comment and my daughter looked bewildered, but was very sweet about it and burst into tears too, which didn't help.
Anyway, all that to say that your heart will be bursting with pride and memories for the rest of your life. But nothing competes with those first few precious hours and days with your very first baby. Congratulations, and soak up every second.
