This instinctive reaction, also known as the startle reflex, occurs when a baby feels a sense of falling. The sudden extension and then retraction of the limbs is a protective measure. Although this reflex may look startling to parents, it’s a normal sign of a baby’s neurological development and usually fades as the baby grows.
Until about 7 months old, babies have the unique ability to breathe and swallow simultaneously. This is possible due to their larynx’s high position in the neck, which changes as they grow, making this dual action impossible in adulthood.
