Hello,
Thanks for posting,
From your description your baby is having the symptom nocturnal
orthopnea which at his age is probably due to congenital heart diseases or respiratory infection which will need that the
pediatrician evaluates the baby again closely. Imagery studies such as MRI,
CT scan, EKG, Heart
ultrasound, Chest x-ray will be needed to determine the cause of the difficult breathing.
If after taking the nasal drop and the child still continuous to manifest same symptom then it is advisable that you go back to the pediatrician. Now, before we go any further, you have to make sure that your baby is actually having
difficulty breathing as it might just be that you are worrying for nothing and that the baby does not have any problems with her breathing except grunting.
Hope this helps
