That comment is a slap in our faces! It's like me talking with someone in a wheelchair that has no legs and saying " I'm so glad I have legs and can walk!" We get these comments everyday and it truly gets to hubby and me AND especially if our son was to overhear! I usually tell people to think about what they just said and if they would like to hear that comment!
Before our son was diagnosed, whenever I heard someone tell me about their child's physical or mental challenge, I would never have said " Thank God my child is normal/healthy!"
All we ask is for people to keep their thought to themselves and yes, thank goodness your child is ok as we parents who have special needs kids go through a lot both mentally and physically raising our children.
Thanks for listening!
