Mazca, I’m trying to remember what I spent on the boys that I didn’t on the girls. Here you go: Tefillin, a kiddush in shul (would have done one in the house if possible), homemade food for the family that came to town for Shabbos (who didn’t for the girls).
We made the same seuda for the girls and their classes that we did for the boys; didn’t do an arts and crafts project for the boys 😉
That’s about it.
(Husband taught the boys how to lain, so no spending there.)
