Does any of your baby has sensitive nose and running nose with either clear or green mucus very often? Are there any natural remedies to cure? I feel like give zrytec medicine, nasal spray or Illadin is not good for long time.

I use Sterimar together with pigeon nose cleaner. On top of that do keep your bedroom clean, change your sheets regularly as well as dry clean your curtains more often. Use an air purifier in the room to remove dust, it'll be better if it came with humidifier so can moist the air and baby's breathing can be smoother. I know of 2-in-1 which can be quite pricey.
