Playing Nice: to think you'd know the baby wasn't yours?

[lover99]

Just seen the trailer for Playing Nice on ITV where the premise is that the babies were switched on accident and the couples left the hospital with the wrong infant.

Am I being unreasonable to think that you would know instinctively that the baby wasn't related to either of you?

Playing Nice is based on the book by J P Delaney
It's not based on a true story although obviously there have been true stories of babies being swapped in hospital
