Is ghusl obligatory for children who have not reached puberty when performing Umrah, and what should a woman who frequently passes wind do if that happens during tawaf or prayer in the Haram?

It is recommended for a child to perform ghusl (definition) (ritual bath) before entering into the state of ihram (definition) for Hajj or Umrah (definition), but their Umrah and Hajj are valid if they omit it. If the emission of wind (flatulence) is constant, such that it does not cease for a period sufficient for ablution and prayer, then it is considered to be like incontinence (sils), and it is obligatory to perform wudu for each prayer at the beginning of its time, and the emission of wind thereafter does not invalidate it.
