I find it helpful to take one step at a time.
DH and I had decided early on we would have no children of our own; yet, we would "foster" and/or adopt children already here and in need of Love. We did just that. It was just right for us.
We were also heavily into the training of Service Animals, as well as strategizing for changing laws for greater accommodation of both Service and companion animals in rental housing. This was a major undertaking.
Follow your Heart.
