Patient's question:
Baby is three and a half months old, cannot hold their head up, can only lift it for a few seconds, eats their hand when lying down, does not look up. What could be the reason?Doctor's answer:
Hello, according to normal growth and development, children usually start lifting their heads at around 3 months. Based on your description, the child can lift their head, but they cannot maintain it for too long, which may be related to personal constitution or vitamin D deficiency. It is recommended to get more sun exposure, maintain normal feeding, and continue to supplement vitamin D for the child. Vitamin D can promote calcium absorption and utilization in the child's body. Biting hands is mostly a habitual behavior, and parents can correct it by intervening and diverting the child's attention.
