Bed-sharing toddlers have increased risk of asthma

Toddlers who climb into bed with their parents have an increased risk of asthma in later childhood, a study has found.

The same association was not seen in bed-sharing infants, say researchers who were unable to provide a clear explanation for their findings.

One theory, that parents who notice wheezing symptoms in their children are more likely to keep them close by at night, was not confirmed by analysis.
