Iv been watching corrie on tv and it made me think, what would I do if i found out that my son/daughter were NOT my kid/s and that in fact they had been switched at birth

.........horrified!!! well for one they would still be my kids, but i would also be curious of my biological child, would'nt you?
dont get me wrong i would not love my kids any less but it would certainly want me to know about the other child....!
comments?
