Hello doc...my baby is 4.5 months old and is having congested nose. I am putting saline drops 2-3 times a day and clearing out mucus with bulbs but still he is having congestion in the nose. Since the temp is high here so we need to make him sleep in AC as he sweats alot and irritated if kept without it. so kindly suggest what can be done to congest him even in cold environment.
