Fathers can make a huge difference in the health and well-being of their infants by supporting breastfeeding and safe sleep practices, a new study has shown.

According to the study published in the journal Paediatrics, among fathers who wanted their infant's mother to breastfeed, 95 per cent reported breastfeeding initiation, and 78 per cent reported breastfeeding at eight weeks.

It is significantly higher than the 69 per cent of fathers who had no opinion or did not want their infant's mother to breastfeed - 69 per cent of these fathers reported breastfeeding initiation and 33 per cent reported breastfeeding at eight weeks. The study included 250 fathers who were surveyed two to six months after the birth of their infant.

"Our findings underscore that new fathers are a critical audience to promote breastfeeding and safe infant sleep," said lead study author Dr John James Parker, an instructor of paediatrics at Northwestern University in the US.

"Many families do not gain the health benefits from breastfeeding because they are not provided with the support to breastfeed successfully. Fathers need to be directly engaged in breastfeeding discussions, and providers need to describe the important role fathers play in breastfeeding success," he added.

Moreover, the scientists also found that 99 per cent of fathers reported placing their infant to sleep, but only 16 per cent implemented all three infant sleep practices (using the back sleep position, an approved sleep surface, and avoiding soft bedding). Almost a third of fathers surveyed were missing at least one key component of safe sleep education.

In the US, over 3,000 infants die as a result of sleep-related causes each year. "Fathers need to receive counselling on all the safe sleep practices for their infants," Parker said.
