This prayer of the SheLa”h is supposed to be said by parents before Rosh Chodesh Sivan (new month of Sivan) this Sunday. Yesterday and today were the days to say it, as prayers making specific requests are usually not said on Shabbat. If you know of another translation, please send it along.
In my previous post I mentioned that the upcoming holiday of Shavuot is associated with bridal imagery. According to Artscroll we say the prayer now because on Shavuot, we also remember that we are God’s children. Shavuot commemorates the day the Jews received the Torah.
