Why this Indian couple's kids were taken away by Norway authorities

A couple from Kolkata is going through a nightmare in Norway. Their two children - a three-year-old son and a girl who is now just one - have been taken away from them by Norway's child protective services. This, apparently because the couple were not bringing the children up properly. What did they do wrong? They fed the children with their hands and the infants slept in the same bed as the parents. The Indian Embassy in Oslo has tried to intervene but with little success so far. The children were taken away last May.
