When does startle reflex go away when sleeping?
How Long Does the Moro Reflex Last? Moro reflex is most prominent in newborns. But this startle reflex gradually gets better and typically completely disappears by month 5 or 6. Typically by week-6 your baby’s neck muscles get stronger and their overall balance and ability to support themselves starts to improve.
When do babies stop jerky movements?

Can I let my newborn sleep on my chest?
While having a baby sleep on mother’s (or father’s) chest whilst parents are awake has not been shown to be a risk, and such close contact is in fact beneficial, sleeping a baby on their front when unsupervised gives rise to a greatly increased risk of Sudden Infant Death Syndrome (SIDS) also known as cot death.
How do you know when Moro reflex is gone?
Once the neck can support the weight of the head, at about 4 months of age, babies start having fewer and less intense Moro reflexes. They might only extend and curl the arms without moving the head or legs. The Moro reflex disappears completely when the baby is 6 months old .
