My 2-year-old daughter has red cheeks, a red chin, and a red hand. What could it be?

It is possible that the redness on your child's cheeks, chin, and hand could be due to dry skin, especially during this time of year when the air is drier. You can try using a gentle, fragrance-free moisturizer to see if that helps. If there are no other symptoms and your child is eating well and not unusually tired, there may not be a need to worry. If the situation changes or other symptoms appear, it would be best to contact a healthcare professional for further evaluation.
