@kamaa. If you read my post you would have understood what's my take for mother tongue.
Mother tongue= the language being spoken by the mother.
So,if the mother is speaking Italian in the present day when the kid is first learning how to speak,then that would be the son's/daughter's mother tongue.
Advocating kimeru /dholuo /kiuk / kamba / taita when the mother doesn't speak any,that's advocating for tribal language and NOT mother tongue.
If the kid learns Gujirati from the mother as the FIRST language,that's the kid's mother tongue.
That's the fabric of it. As bare as it can get.
