If, however, you find your health affected by keeping the Fast the Guardian would advise you to consult a physician, and if he tells you you are unable to fast then of course, you should abstain from doing so.

He (the Guardian) feels that Bahá’í children like you have a lot of wonderful work to do for others in the future. But you don’t even have to wait until you grow up, you can help your dear Mother teach the Cause to others right now, and also tell your playmates about it. The Guardian is going to pray that you may grow up to be a shining light in the Cause of Bahá’u’lláh.
