Fitra must be given on behalf of all members of your family.  It is also obligatory to give it before the Eid-ul-Fitr prayer because of the report narrated by Abu Dawood (1609) and Ibn Majaah (1827) from Ibn ‘Abbaas (may Allah be pleased with him) who said: The Messenger of Allah (peace and blessings of Allah be upon him) enjoined zakaat al-fitr as a purification for the fasting person from idle and obscene talk, and to feed the poor. Whoever pays it before the (Eid) prayer, it is accepted zakaah, and whoever pays it after the prayer, it is (ordinary) charity. Classed as hasan by al-Albaani in Saheeh Abi Dawood.
