Dear sir/madam my daughter is 6 months old. While feeding or while playing her hands and feet are becoming cool (sweaty). I went to pediatrician and consulted him. He doubted that cardiac murmur. I went to echo and finally declared that very tiny hole is present in heart. Doctor suggested that it will be cured when the baby grows. The hole is very very small. Her weight is gud. No other symptoms. No need of surgery or medication. Please suggest me any advice.
