Super cute, congrats !!!! Welcome in "The Club of Those Who Never Sleep. Ever. Again."
When I was pregnant with N°1, I went to one of these (horrid imho) preparation class. The ony thing I still remember, and the only thing that indeed applied and still does, was "To have a child is to have for the rest of your life you heart outside your body" (the midwife said the equivalent of this in German, I can only translate it poorly, it was much more lyrical than that actually).
I did not get it then, but as soon as he was born, I fully understood it and today, my heart has cloned itself so there are two of them and they are both walking outside of me.
I think there is nothing better in life as having a child (or more if you want/can) and raise her/him/them and watch them grow.
And mind you, I did not even want children when I met my husband...
