I should mention, maybe, that this is an extremely family-oriented community, where the majority of moms are SAHMs, volunteer in the school, etc. ....
Sorry... sore spot for me

...it's not just the SAHM's that are family-oriented. Nor does being SAHM make you a more involved parent. Just as being a Working parent does not mean you are not involved.
I'm a working mommy (because I "want to" not because I "have to") and I'm still very involved in my kids lives and schooling.
(I'll get off my soapbox now...I feel the need to rant when anyone equates "SAHM" to a "better" mom in any way/shape/form. <exhale>
This is so true, and a sore spot for me as well. I am a family physician, and I volunteer lots for school, scouts and church. Family physicians actually work quite long hours and the work is really quite demanding. I am a member of the school commission, and my husband and I helped to establish a science lab for the middle school aged students at this school. On a regular basis, my husband, another science trained father and I give presentations on science topics as enrichment for the students. In order to do this, one needs to have the appropriate background and training, which in my experience, most SAHMs do not have. (I am sure there is a rare PhD chemist SAHM, I am not referring to her).
