Be happy. Be kind. Be appreciative. Don't be a ho.
But since this is going into the baby book, it should be fluffier than that. So, this is what I wrote:
Dear Olivia Marie,
You are my favorite person, other than your dad. Being your mother is my greatest adventure, one with twists and turns popping up just when I set the cruise. You are loved- unconditionally by me, purely by your father, intensely by your grandparents. I can't wait to watch your personality develop, to hear your thoughts and observations on the world around you, to hear the sound of your voice when you sing your favorite songs in the car. You are still in many ways a stranger, but I have never known anyone quite as well as I know you.
My job is to nurture you, provide for you, and prepare you to be a contributing member of society. In order to do this, you will be given discipline instead of bail outs. There will be times you don't like me much. Sorry, not sorry.
Remember that your brain is not fully developed until you are 25, so try to refrain from permanent decisions (husband, tattoos, babies, etc) until after that time. Your decisions will affect me, because your health and happiness affect me. When major forks pop up in the road, use your gut to make the call on the direction you take. Your instinct is a gift and it's usually right.
I pray you give love to and accept love from yourself, friends, family, animals and, one day when you are old enough, your soul mate (who I do believe exists).
Mistakes will happen. Many of them have the potential for life-altering consequences that don't appear positive, but it's not the end of the world. You can always recover if you choose to. You will probably hear that "everything happens for a reason". I'm not sure that I believe this, but I do believe that sucky stuff happens & you can choose to respond to it in a positive way (after allowing yourself to be angry about it for a little while).
While I am writing this, you are a toddler asleep in your crib. I know that the time I have to raise you will go quickly even though many of the days will seem long. Even in the hardest of times, I will always be happy in the deepest part of my soul that you are part of my life.
I love you,
Mommy
And yes, it was too long!
