#AskTheExpert Hello sir meri baby 4month ki hai uske dil me chhed hai or use bhut jyada pasina aata hai mujhe kya krna chaiye

A. hi dear Before birth, all babies have a natural hole between the upper chambers of the heart. This hole is called fossa ovalis. In most babies, the hole closes before birth as a natural flap seals shut. In some cases, this sealing will not occur until a week, or even several months, after a baby is born.
