Jon and Lindsay McHale, both 33, were stunned when they saw a familiar face pop up on their baby Madison's scan.
It looked just like Jon's grandmother Kathy.

Speaking with The Mirror, Jon explained: "We didn't see it at first but my mum was in the hospital with us and she said she had seen it on the screen.
"She told us to take it home and watch it, and that's when we noticed it.
"I like to think there is a relative watching over Madison and we think the face looks a lot like my grandma Kathy."

Apparently Madison, who is now six, likes to watch the 4D scan video to see her very own guardian angel for herself.
Jon said: "We have to point out the face to her but she always does a little smile and then gets a bit embarrassed."
