Any home remedy for my one year for runny stuffy nose? I've been putting Vicks on his chest and feet and running the humidifier but his little nose is like a faucet. I read something about a potato in his socks at night? Anyone ever try this? But I'm not sure if that's just for fever or not. I have been putting saline spray in too.
