Children who snore loudly at least twice a week are more likely to misbehave, it has been claimed. The risk of hyperactivity and inattention increases in young children who are persistent and loud snorers at early age, warns Dean Beebe, a neuropsychologist from Cincinnati.
Dr. Beebe's study, published online in the medical journal Pediatrics, questioned the mother of 249 young children about their youngsters sleep and behaviour. The study found children who snored loudly at least twice a week at the age of two and three had most behaviour problems, including hyperactivity, inattention and depression.
Dr. Beebe said that breastfeeding, especially over longer periods, could protect children against persistent snoring, even after taking into account other factors including family income. Dr. Beebe said: "A lot of kids snore ever so often, and cartoons make snoring look cute and funny. But loud snoring that lasts for months is not normal, and anything that puts young kids at that much risk for behavioural problems is neither cute nor funny. That kind of snoring can be a sign of real breathing problems at night that are treatable. I encourage parents to talk to their child's doctor about loud snoring, especially if it happens a lot and persists over time."
Dr. Beebe also pointed out that "the strongest predictors of persistent snoring were lower socioeconomic status and the absence or shorter duration of breastfeeding. This would suggest that doctors routinely screen for and track snoring, especially in children from poorer families, and refer loudly-snoring children for follow-up care. Failing to screen, or taking a 'wait and see' approach on snoring, could make preschool behaviour problems worse. The findings also support the encouragement and facilitation of infant breastfeeding."

well, they 'misbehave' in their sleep, so the possibility shouldn't be ruled out

Nonsense
