I have come to realize that adopted children are loved just as much as a natural child and that makes me glad since I have been adopted into God's family.
No parent wants to miss bonding with their child and watching their child grow. You want to be available for your kid during critical life issues and special events.
It can be a large burden for a child to have to undertake a caretaker role that would be expected for someone more in adulthood. You might, in some ways, end up having (the child) sacrifice their opportunity to be a child.
When we went into foster care this last time we talked to our children about our desire to adopt and they were all excited about the possibility.
