Mums-to-be who smoke may find their babies have increased chances of sleep problems throughout childhood
Smoking in pregnancy linked to baby sleep problems
A study in America has found that babies exposed to smoke and nicotine in the womb are more likely to struggle with sleep, reports NDTV.
Out of 808 children involved in the study, 374 were born to mums who smoked during their pregnancy.
This group were found to be more likely to have trouble falling asleep and were less likely to stay asleep through the night.
These findings remained the same for different ages, from 1 month up to 12 years. The link remained even when social and economic factors including medical care were taken into account.
This adds to the growing list of problems associated with smoking when pregnant.
