London, Aug 4 : Madonna's adopted son David has a baby brother back home in Malawi, after his natural father Yohane Banda remarried.
His brother Dingiswayo was born on July 19, and Banda has asked two-year-old David for help in bringing up the baby by sending educational items for him.
Banda, 33, is a peasant farmer, who earns only 50 pounds a year and lives in a mud brick and grass thatch house, growing tomatoes and doing odd carpentry jobs.
When giving up for adoption he had expected Madge to support his family financially and was very "disappointed" when she did not.
It will be a totally opposite kind of life that David's little brother Dingiswayo will have to face.
"I ask David to help his little brother, especially in sending education materials so that he has a bright future. It is an obligation for David to help his young brother and people will not be surprised at this request," the Daily Mirror quoted Banda as saying.
The other thing worrying Banda are the reports that Madonna's marriage to film director Guy Ritchie is on the rocks.
He has told his friends that he will "move heaven and earth" to get David back if they split.
"I am quite scared of the talk of her marriage break-up because that may affect David. I will act accordingly if I think something serious could happen," he said.
