18mth old DD is always snotty. When she goes to bed you can hear the catarrh rattling at the top of her nose, which then makes her cough. Tried the vapours and pillow raise, to not much avail. Tried the suction gadget, but she howls about it.
Has anyone tried cutting out dairy in this situation. Obviously not something I would do rashly - wouldn't want to cut an important nutrient on a whim, and don't want her to grow up with and unnecessary dietary prohibition. Is this an effective option or just McKeith-style mumbo-jumbo?
