Dear Big Brother Z,
Today, my eldest son, you are four years old.
It's hard to believe that four years have passed since you came into our lives. I don't really remember what life was like before you came along. I feel as though you have always been with me.
You are really coming into your own. I see your personality further developing and I could not be more proud of the kind-hearted boy you are. Your teachers say that all the girls at school like you and they think it's because of your kindness. That makes my heart smile.
You sure can be a challenge though. I know those times are just you exercising your independence from your daddy and me, and I try hard to stay patient and try to teach you about the world. You already have so much figured out.
I can't wait to see how your interests develop. I know you already have a story and I can't wait to see how it's written. Will you continue to love to swim? Will you excel at karate since you "want to be a ninja and save the world"? Will you like sports? Or music? Will you be a scientist since you have shown interest in experiments? Only time will tell, and while I wouldn't wish your youth away for anything, I am so excited about what the future holds for you.
You still ask me to stay with you in bed until you fall asleep. While I sometimes wish I could say goodnight and leave, that time at night is so precious to me. You like to talk for a while, then have me sing Three Little Birds, then lay with you until you fall asleep. You are honest and vulnerable at this precious time, and I learn so much about you right before you fall asleep. I wouldn't change it for the world.
You teach me to keep life simple. That nothing can cure hurt feelings like a kiss and a piece of chocolate. That I am getting older. That we all need to ask for what we want (like when you get in trouble and tell me "I'm so sad mommy, I need a hug").
You made us a family four years ago, and you continue to teach me about what is really important in life. I love you so much, BBZ.
