Erev Rosh Chodesh Sivan, which is this Thursday, is the eve of the new Jewish month in which the Jews received the Torah. This is a very special time to recite this parent's prayer. http://www.metroimma.com/forum/topics/special-prayer-for-parents-to-recite-erev-rosh-chodesh-sivan
This link has the prayer in both English and Hebrew.
Much Love and Blessings!
