From the MDHS Division of Family and Children Services adoption page:

Who are the Children Waiting for Adoption?

All of the children available for adoption through the Department of Human Services have one thing in common: Their biological parents are no longer able to care for them.

We have very few infants or toddlers available for adoption. Most of our children are six years of age or older. Many have brothers and sisters who are also available for adoption. Some children have emotional, mental or physical needs. Others have chronic medical conditions. All need loving parents who can accpet them as they are.
