We've been using the nose sucker like crazy he's so snotty I could just keep going for what seems like hours sucking snot...it's insane and happened over night. He went from happy healthy fun baby to crying congested sick little dude today.

like @mommyof2_94 said, also use saline drops for babies, and use the booger sucker a couple times a day to get the icky stuff out.... sit in a steamy bathroom if you notice it in his chest as well

& if u have a vaporizer use it for him

vapor rub on his chest & feet cover him up with a sleeper, also a little bit of vapor rub on his nostrils so he can breath a little better
