What is minimum neck stretch reacquired for new born baby?

Newborn babies have limited neck mobility and typically cannot support their heads on their own. The minimum neck stretch required involves gentle movements to promote range of motion, such as turning the head side to side and gently lifting it while the baby is lying on their stomach. It’s important to handle their neck with care, as their muscles and ligaments are still developing. Always consult a pediatrician or a physical therapist for specific guidance on exercises or stretches appropriate for your newborn.
