Clamping the cord early or late does not affect a mother's risk of blood loss during birth, a Chochrane Library review reveals.
A review of 11 trials with nearly 3,000 mothers and babies found that delaying cord clamping for two to three minutes after birth does not up the risk of excessive bleeding for the mother.
Instead, delaying cord clamping is thought to help increase the baby's red blood cell levels in the first few months of life.
If a newborn's liver struggles to break down the increase in fetal red blood cells, phytotherapy can help to speed this process up.
Lead researcher Susan McDonald said: "If there is access to phototherapy treatment, there would appear to be no additional risk in delaying clamping the cord in healthy term infants, particularly as this appears to boost the infant's stores of iron.
"This may be of particular benefit for babies with poor nutrition."
