She Snores a Lot
Sometimes a child's naturally large tonsils and adenoids can partially obstruct her airway while she's sleeping—causing snoring but not actual sleep apnea. "The tendency to have obstructed breathing can be hereditary," says Dr. Manning. If you or your husband snored a lot as a kid, your child may be following suit. When she's sleeping, the muscles of her throat relax, and the amount of space for airflow around her large tonsils is reduced. So you'll hear your child snoring, but you won't hear the startled gasp or see her moving around several times a night, as a child with apnea would.
She'll also seem well rested when she wakes up.
The good news is that your child's tonsils and adenoids will naturally shrink as she gets older (usually around the tween years), so her snoring may fade away over time. If it doesn't, but she has no other signs of tonsil or adenoid issues, it could be that she was simply born with excess tissue in her throat and is naturally prone to snoring.
