This toddler sleep problem could be caused by sleep apnea, a potentially dangerous condition in which your child stops breathing repeatedly while asleep. Take your child to a pediatrician, who may recommend your child be evaluated by an ear-nose-and-throat (ENT) specialist.
"Safety is the first thing to look out for in situations like these," Zafarlotfi says. "Make sure the crib or bed is as safe as it can be so children can't hurt themselves." Line the crib or wall by the bed with pillows so your child doesn't hurt his or her head, for example. "If this continues to the point that the child is disturbed, see a sleep specialist for a sleep study," she says. There are many potential causes of this toddler sleep disorder. "It may be a psychological issue, it may be something that they will outgrow, or maybe they are having seizures while they sleep." Depending on the cause and the severity, medication may be in order.
