You have a 3in 1 question here but they are very good questions. Firstly a 6 year old girl can certainly develop vaginal thrush especially if she has had an antibiotic recently. Give her a probiotic such a Probiflora for children for at least 10 days. Also give her Nystatin drops by mouth 1ml daily for 5days and apply Nystatin cream to her vaginal area twice a day until she is better.Do not use bubble baths as this is a frequesnt cause of lowering the natural defence barriers against thrush.Thrush is not caused by fizzy drinks.
Your daughter is grinding her teeth. This is called bruxism and is a very difficult habit to stop. The good news is that it usually stops when the permanent teeth are through.If she continues when she has her permanent teeth she must see a dentist.
Your daugher's chest pain is a very common complaint and is usually due to stress or tension. It is caused by spasm of an artery on the inside of the chest wall. It is not due to a heart problem. She needs reassurance and if she is indeed a tense and stressed little girl she may need counselling by a child psychologist.
