The Moro reflex is a protective “primitive reflex” seen in healthy babies up to 6 months old.
The Moro reflex typically disappears by the age of 6 months.

Triggering the Moro Reflex
The Moro reflex is a “startle reflex.”

Anything that intuitively causes alarm can activate a baby’s self-preserving survival instincts and instantaneously trigger this reflex.
Infants can even startle themselves to trigger a Moro reflex.
When Do Newborns Grow Out of the Moro Reflex?
A loud clap also may elicit the response.
Physical contact is comforting and promotes attachment security during infancy.
Keep in mind, though, that the startle response is normal within the first few months.
It typically starts to disappear about two months after birth and is usually totally gone within six months.
Holding a baby close and making them feel safe calms the Moro reflex.
This may be identified at birth or become apparent later.
Talk with your healthcare provider about any Moro reflex concerns.
