Thanks for the reply, it is a baby tooth that needs to come out, they x rayed it a few weeks ago and said it was likely to come out on its own within the next month but if she had any issues with it then to go back and have it pulled, dd has asked to go back to the dentist as it has started to hurt her.
My youngest dd had two small fillings last week in the morning and went to practice in the evening, she was ok, she came out after warm up/conditioning saying she had a tummy ache and felt sick, she had just done some new core exercises that were heavy duty and after a pain killer and cuddle she went back in and finished her practice, we weren't sure wether it was the tummy muscles or dentist treatment earlier in the day that caused the tummy ache and sickness feeling. My money is on tummy muscles as she felt better after the pain killer kicked it, if it was sickness she would have not gone back in. It is hard when they are young to tell the difference between tummy muscles pain and tummy ache.
I will see how my oldest dd is tomorrow, I will still take her to the gym if she is not sure if she wants to go in (just to watch and get last minute details for her competition on Saturday) unless she feels really bad, then she will stay at home.
