The morning after she had her son, he was brought back to her and she noticed something different about him.

She suspected she had got the wrong child. But doctors insisted it was the right baby and blamed her suspicions on the medication she had been given during and after her labor.

After a few days Mercedes and her husband Richard flew home to Texas, with their baby, but as the child grew, he looked less and less like either of them.

DNA test

Finally, Richard and Mercedes decided to have a DNA test to find out the truth once and for all.

When the results came, their suspicions were confirmed, the child they had been raising for nine months was not their son, writes The Guardian.
