Toddlers who share a bed with their parents might have an increased risk of asthma in later childhood, new research has suggested. The authors found that children who had bed-shared during infancy (at age two months) did not have a higher risk of wheezing during their first six years of life, or of getting diagnosed with asthma. However, bed-sharing at the age of 24 months was associated with an increased chance of wheezing subsequently (at ages three to six years), and with an increased chance of being diagnosed with asthma at age six.
