A baby who keeps kicking the blanket while sleeping at night may be due to a calcium deficiency. Treatment methods include general treatment and calcium supplements.

A seven-month-old baby frequently wakes up at night to breastfeed, disrupting his nighttime sleep. Possible reasons include hunger or a deficiency in vitamin D and calcium. It is recommended to expose the baby to more sunlight during the day, supplement with cod liver oil and calcium, and observe for a week to see if there is any improvement.
