It is best not to hug vertically within three months, which is not good for the baby's spinal development. The baby's spine is almost vertical, but the normal adult's spine is S-shaped, with four physiological bends: neck, chest, waist and sacrum. Physiological bending of spine is of great significance, which can maintain normal standing posture, balance limb movement, bear weight, exercise to cushion impact and protect spinal cord.
Babies' bones contain less calcium and other salts, and their spines are flexible, without the curvature peculiar to adults. The muscles of the baby's spine and back lack support ability, and it is easy to deform the baby's spine if it is held too early. The baby can be held for 2-3 months, but not for too long.
When the baby is holding vertically, he must hold his neck with his hand to prevent the cervical vertebra from being damaged. You can also try to put your baby's back against your chest. You can support your hips with one hand and lift your baby from the underarm ring with the other hand, which will not only broaden your baby's vision, but also make your baby's neck stand up faster without damaging the cervical spine.
