Hi doc.i here a voice from my 6 months old babies nose while feeding and also when he lies straight on a bed. when i keep him in upright hes ok .

Noise: Do you mean noise ? Noises from the nose. Are common when feeding. The little sphincter in the back of the nose is developing. This will get better with time. If not see an ENT doctor. If he or she is developing well and are gaining weight and. Reaching appropriate milestones, i would not worry about it much. Hang in there.

Adenoid or reflux: He might be having some reflux into his throat or back of nose which is usually worse during feeding or laying down. A large adenoid could also cause similar symptoms. As long as he breathes through his nose, doesn't snore, feeds without coughing or choking, it should be ok to watch. See md if concerned.
