Night time congestion

Abry

So I've begun to notice that my 5 month old seems to get somewhat congested at night and he fusses because he's unable to fully breathe. I'm usually on top of making sure his nostrils are clear, but it still ends up happening. What can I do to help him, especially when there's nothing to pick out of his nose?! When he feeds, he sounds somewhat normal.

I'm trying to figure this out before I go to his pediatrician.
