Scientists say they have solved the mystery of why mothers tend to cradle newborn babies on the left. This position activates the right hemisphere of the brain, which is involved in functions that help in communication and bonding, they say.
The “positional bias” is not unique to humans, with their advanced brains, but is also found in animals, according to researchers in Russia. Similar behaviour has been seen in baby mammals following their mothers. They include kangaroos and horses on land and walruses and orcas in the sea.
