All newborns are born with a number of normal baby reflexes. Moro reflex, also known as startle reflex, is one of them. You may have noticed your baby suddenly “startling” while sleeping before. This is the Moro reflex (startle reflex) at work.
Why does my baby startle so easily?
“The startling reflex, known to physicians as the Moro reflex, is usually caused when your baby’s head changes position or falls back abruptly, or when she hears a loud or unusual noise,” explains Rallie McAllister, MD, MPH, a family physician and coauthor of The Mommy MD Guide to Your Baby’s First Year.
How do I know if my baby has Moro reflex?
When checking for the Moro reflex, most physicians use a test known as the head drop. During this test, the doctor mimics the sensation of falling by raising, and then slowly lowering, the baby’s head below the level of the body.
Is it normal for babies to be jumpy?
Jitters or trembling of the arms and legs during crying is normal in newborns. It should stop by 1 to 2 months of age. If your baby is jittery when not crying, it could be abnormal. Give her something to suck on.
Is the Moro reflex bad?
The Moro reflex is a normal, involuntary response in newborns and infants. However, you should speak with your doctor if you notice that your baby still demonstrates the Moro reflex past the age of six months, or you suspect that their reflex is triggered more often than normal.
When do babies grow out of startle reflex?
Your baby’s startle reflexes will begin to disappear as they grow. By the time your baby is 3 to 6 months old, they probably won’t demonstrate the Moro reflex any longer. They’ll have more control over their movements, and their reflexes will become less jerky.
When do babies stop jerky movements?
Babies usually display rooting, sucking, startle, grasp, and tonic neck reflexes soon after birth. These reflexes are involuntary movements that are a normal part of infant development. These early reflexes gradually disappear as babies mature, usually by the time they are 3–6 months old.
When do babies stop startling?
The good news is that the startle reflex usually disappears after around 3 or 4 months, but this may be later for some babies. This is why we are encouraged to swaddle babies from birth until the startle reflex has disappeared.
When does Moro go away?
Over the first six weeks of your baby’s life the reflex starts to happen less frequently, and, according to HealthyChildren.org, the Moro reflex will most likely disappear completely by the time your baby is 4-6 months old. One of the ways your baby lets go of that reflex is from your constant comfort and protection.
When will my baby’s reflux stop?
Reflux is very common in the first 3 months, and usually stops by the time your baby is 12 months.

At first, a newborn’s stomach muscles are not strong enough to do this, so they use the diaphragm muscle to move their bowel. As they exercise the diaphragm, it can put pressure on the voice box, resulting in grunting.
When should I worry about baby twitching?
If the twitching stops immediately upon waking, it’s likely harmless myoclonic twitches. They won’t continue when the baby isn’t asleep. If your baby is experiencing twitching movements or stiffening when awake, you may be dealing with a seizure issue such as: Infantile spasms.
What happens if Moro reflex doesn’t go away?
If your baby’s Moro reflex doesn’t go away after six months, this could be a sign of other problems such as a delay in the development of their motor skills or cerebral palsy.
What happens when the Moro reflex doesn’t go away?
If a child experiences a retained Moro reflex beyond 4 months, he may become over sensitive and over reactive to sensory stimulus resulting in poor impulse control, sensory overload, anxiety and emotions and social immaturity.
What is startle reflex PTSD?
The acoustic startle response (ASR) is a subcortical reflex modulated by neural systems implicated in posttraumatic stress disorder (PTSD). ASR is conserved across species and is increased in rodent models of developmental stress.
