Sayyiduna Jabir (may Allah be pleased with him) said that the Prophet (peace and blessings be upon him) "granted a concession regarding the slaughtered animal of a woman, and of a child or a boy, when they slaughter it saying the takbir."
This chain has weakness in it. Al-Waqidi corroborated it regarding the slaughter of a boy, and he too is da'if (weak).
