Hi I have a 7 weeks old baby he's got a really bad cold he keeps coughing and sneezing his nose is blocked and he isn't getting much sleep . I spoke to my Health Visitor and I said could I use oilbas. Or vic for baby's and she said not really lets just see how he gets on. But he doesn't sleep or stop crying I've took him to see a doctor and they give me drops for his nose but there not working. What can I use please help
