A new study from the Journal of Health Economics claims that babies who look like their fathers are more likely to be healthy.
The study says that fathers are more likely to spend more time with their kids if they look like them, as they're more confident the child is genetically theirs. On average, a father will spend 2.5 days longer with their child per month if they have similar looks.
"Fathers are important in raising a child, and it manifests itself in the health of the child." the study says.
"Those fathers that perceive the baby’s resemblance to them are more certain the baby is theirs, and thus spend more time with the baby,"
So simply spending more time with time with the child makes them healthier.
“single-parent households are at a disadvantage, which likely affects them throughout their lives,” the study also claims.
