why is my baby having congestion quite frequently, say like in a 2 days interval. Though I give him medicine whr he has congestion and saline, still again after medicine within few hours he has congestion. With medicine it gets cured in one or 2 days and again in a gap of 2 or 3 days, he's having congestion again. Is it because of the climate or he has hard cold in his chest right before birth itself? If so, could you kindly tell me remedies to complete eradicate his problem?
