Surely one recognises their own baby?
In the past, nurseries were used in hospitals while mothers recovered for a few hours, but wrist and ankle bands were used with the baby's name on them.
Often a baby looks just like its parents , and mothers can even 'smell' their own baby.
What a horrible shock to find out your baby isn't ''Yours''.
I too don't think these DNA 'Ancestry' tests are a good thing.
''Jeremy Kyle'' used to do them , probably as it was 'entertaining' for the TV audience.
''Our DNA test says that you are NOT the child's father! Neither of you are! It is someone else...''
Cue both men running off, and the woman crying saying ''It can't be true!''
Never mind the poor child.
