Oh I've not tried the nose drops. I use Calpols nasal spray which I've found helps & the snuffle babe ointment which you can put on their chest. I put it on a muzzy in with them while they sleep.
oo right didnt know they had a age you should be okay using it then maybe put it in a bowl of hot water and leave it in the room use are sitting in thats what I do with my daughter xx @abbiegale
