We are going with my niece to Thailand, my mother has issued a notarized consent to accompany me, but mother and child have different surnames. Do I need to certify a copy of the child's birth certificate?

After all, the power of attorney contains the mother's data and birth certificate? If yes (and there is no other way), then that's enough.
