Breastfed babies have bigger brains

MORE benefits of breastfeeding have been uncovered by British anthropologists who found breastfed babies have bigger brains. 

The Durham University team analysed evidence on brain and body size in 128 mammal species including humans, whales, gorillas and elephants.

The longer the pregnancy and breastfeeding period in mammals, the bigger the baby’s brain grew.

Fallow deer, who are pregnant for seven months with a suckling period up to six months, have a brain six times smaller than humans with a gestation of nine months and suckling period up to three years, despite having the same body weight.
