Please know that my daughter and I are very very close. I spend every free moment with her, playing, riding bikes, going to the library, etc... She has a bit of time each afternoon that she spends playing with Poppa. I just worry that she won't have enough if she doesn't have me and my parents.
I would not have another child to take care of me in my old age. I would have another child so my daughter has a sibling when our family shrinks even further and has someone to hold her hand and "remember when mom...." at my funeral.
