Question
With heavy winter clothing, how can you effectively expose babies to sunlight to prevent calcium deficiency?
Answer
Newborns should not be directly exposed to outdoor sunlight. Instead, they can receive indirect sunlight through windows indoors, with 1-2 sessions daily, each lasting about 15-30 minutes, to help synthesize vitamin D and prevent rickets. Remember not to use glass or curtains, as this can weaken the effect of ultraviolet rays. As the baby grows older, you can gradually extend the duration and range of sun exposure, but the head and face should be protected from direct sunlight.
