My poor little one has a terrible cough and cold. Her nose is running constantly, she must have a sore throat because she sounds croaky and coughs continuously when lying down. We are now on our 3rd sleepless night and as much as I feel so sorry for her, we are all desparate for some sleep! I've tried raising her mattress slightly, and also some Karpol on a hanky tied to her cot. Help!
