It is allergy season, maybe baby has allergies
Could i give him any medication his a newborn
Call his pediatrician. They will know best, but i dont think so. I would run a hot shower and sit with the baby outside of the shower to try and clear up his passages. Maybe put some baby vicks on him too
Sometimes newborns sneeze alot and have a lot of mucus in their respiratory system left over from birth sneezing is jow they get rid of it. I wouldn't give a newborn any medication though unless you talk to a pediatrician first.
Bring the kettel in front room n boil it n leave it open tho n the steam will clear babys nose its wat I do
