Poor little thing has had a D&V bug for about 2 weeks now. Thought we were over and done with it about a week ago so I hired a carpet cleaner and the smell went away. Unfortunately he has had a couple more vomits and I really don't want ot hire the carpet cleaner just for one patch in his bedroom but the smell won't go. Have tried dettol, washing powder, am going to try bicarb today - any other tips?
