If you're a parent of a noisy newborn, it's really nothing that should cause any alarm. Like most parts of their bodies, which are still immature, babies are noisy breathers in general because their nasal passages are still narrow and usual are filled with bubbly secretions. When air passes through these puddles of secretions, a vibratory sound is produced – making us think our baby is "snoring". Baby snoring is basically just a sound produced by the soft tissues as air passes in. As the baby grows older, as well as his nasal passages, and as he learns to swallow excess saliva these vibratory sounds or baby snoring should subside.

* he appears to stop breathing and wakes himself up frequently with his snoring, or continues to snore as he gets older, as this could be a sign of sleep apnea
* If the "snoring" is more of a high-pitched squeak every time he breathes in (possible stridor) or every time he breathes out (possible wheezing)
* If your baby appears to be in distress or breathes very fast when he is snoring
* If he isn't growing well or appears sick in other ways
