Before our son was born, we were given the option of genetic screening, noninvasive in nature. We learned that our baby might have heart disease, be short sighted, grow to be bald, and suffer from a mental illness.
With our second child's weight issues, she had genetic screening done for glucose intolerence. She carries that gene.
If ANY of these conditions arise in our children's lives, we will handle it. We don't see them as objects, they are gifts from God... for us to care for. And later, they will return to Him.
May God's richest blessings be on you and your children.
