A. Well Ma’am actually I was selling the lungs are not developed initially at the time of where the doctor may advised to keep the child into incubator for sometime till the time the proper growth is not there and after that usually problem does not happen but we cannot confirm depending upon how the growth is going how much of the lungs have developed with growing age on that basis only a doctor can confirm
