My son has ulcers in his mouth and a white tongue what should I give him?

I have been putting TCP on them but it has been a few days now- is there anything kids can have or could it be a sign of something else e.g run down. he is 4 yrs old and has just done a few weeks of 4 days a week at school/preschool so is very tired.

I wil take him to the doctors but I wanted to know if anyone knew of something to keep him going until I get him there, since i dont have my car while my partner is at work. I do not appriciate some of the messages there is no need and he does not have thrush becuase I know what that looks like, just a couple of ulcers and that white coated tongue we all get when we are under the weather.

Give him something cold that will make him feel more comfortable. Don't give him any oily food that will make him feel worse. Is better to get doctor's attention on ur son and do according to his advice. Take care. Good luck...
