We have two children here and two babies in Heaven (unexplained stillbirths, two in a row). When we had our second loss, a member of our church wrote in the guest book at the funeral: "God Bless you as you populate heaven". After writing it she was thinking "WHAT HAVE YOU DONE??!!" to herself. My husband and I actually really liked it and found the blessing in it that she meant to impart.
So here we are just newly expecting again. I am nearly 41. The "world" will say 'are you nuts?" Our church family, our home group in particular, are very 'pro-baby' and will be behind us all the way. Several families in our church have 6+children and most agree that kids from bigger families are GOOD kids. The older help the younger, they learn how to share, and so on.
All the best to you in your baby-building!
