This is an important and excellent question and is so well set out.Young children should not snore. If they do snore it means that they have a very blocked nose. This is usually due to enlarged adenoids blocking the nose in children of your daughter's age. In addition she stops breathing at times. This is a worrying condition known as SLEEP APNOEA. She is coughing because of a post nasal drip caused by her enlarged adenoids. Your little girl must be seen by an ENT specialist ASAP. Please make an appointment tomorrow. In the menatime get a Budeflam Aquanase nasal spray and use it twice daily to try to open up her nose. It is really vital that she be seen by the ENT so please do not delay.
