Expatriate health insurance customers who are considering having a second child might want to pay heed to recent warnings.
Dr Sarah Brewer, author of Planning a Baby?, said that the risk of a premature birth is 40 per cent higher among women who conceive a child within six months of giving birth.
The warning comes after a study published in the journal Pediatrics suggested that the risk of a child having autism is higher when the mother has a shorter interval between pregnancies.
Pregnancies that are spaced less than one year apart from each other were found to be at the highest risk.
Dr Brewer advised: "In an ideal world, it's best to recover from the rigours of pregnancy and childbirth.
"It takes at least nine months to build up nutritional status again, as pregnancy increases your requirements for vitamins A, B1, B2, C, D and folic acid."
Expatriates might want to double check their health insurance to see if they are covered for midwifery care.
