My 6 month old baby was sniffling all night, I think his nose is blocked. What should I do? Any home remedies?

Yes dear, sterimar. Even the hospitals use it for infants till child becomes older. If its really congested you can get illadin. Illadin is for nasal congestion, also used at kkh. Otherwise suctioning with a nasal aspirator works as well. Best to combine all together :)
