 This allows food to move closer to the laryngeal vestibule before triggering a gag.Although this allows for increased ability to safely swallow, if oral skills are immature due to lack of practice, this puts older infants at a high risk for choking and aspiration of immaturely chewed food materials into the lungs.Oral motor development would suggest that if an infant does "not" learn how to manage a bolus intra-orally and time their swallow, more choking would occur "after" the age of one, when traditionally more solid foods are added to the child's diet.
