Is it normal for a 4 yr old to snore at times? Or could this be sleep apnea? Is it deadly?

Uncommon. We see this occasionally during a URI or with tonsillitis. But the snoring should subside when the illness passes.Any 4 yo who snores all the time should be evaluated by an ENT for airway obstruction/sleep apnea. If you notice pauses in respiratory activity (>20sec) the kid falls asleep a lot while others are playing, there is a problem and it will get worse without treatment.
