Is it normal for a three-month-old baby to sleep little?

Patient's question:

No

Doctor's answer:

Hello, according to your description, it is likely caused by calcium deficiency. Calcium deficiency can easily lead to baby crying, poor sleep, and you can check for trace elements. You can take fish oil orally to supplement vitamin D, and add appropriate calcium supplements. Also, make sure to get more sun exposure to promote calcium absorption. It will gradually improve. Wishing your baby healthy growth.
