Their pre-Christmas get together on December 14 - the second time Amy has met Grace, but the first time they have gone public - is made all the more special as the little girl has brought a belated gift to mark what would have been Mia Hicks’ 13th birthday on October 22.
Seeing Amy with Becci Westwood, 41, and her charming daughter Grace, five, together on a chilly winter’s day, they look like a happy extended family, enjoying a stroll together in the park.
But when Amy Anderson listens to her daughter Mia Hicks’ heart beating in another little girl’s chest it feels simply incredible.
Mum who donated daughter's heart hears it beat again in transplant patient Hearing the gentle beating of your child’s heart is precious for every mum.
In fact, the story behind this little gathering - which sees them joined by Amy’s son, Mason, nine, and Becci’s son, Josh, eight - is very far from every day.
