The longer a child is breastfed the smarter they are.
This is not new information to those of us involved in the field of human lactation, but its great to hear that this new study by Harvard University has confirmed this.
This is the largest study ever undertaken, which followed 1000 mothers and their children from their child's birth to their seventh birthday.
The study also found that mothers who ate more fish whilst breastfeeding than those who ate less fish, this also assisted with the child's intelligence. Fish is a good source of protein, B12, iron and omega-3 (omega-3, assists with brain development).
The study was published in the JAMA Pediatrics
