Perhaps volunteering at the school, as has been suggested here, would help w/ any guilt one may be feeling over asking for accommodations for DC. Freeing up the teacher's time can be a big help. Also, the year I taught science in DS's 2nd grade class on a semi-regular basis, I was kept privy to the goings on by the teacher - like when the testing would occur etc when none of the other parents were notified. But this year, w/ DD22mths, I'm not able to do that so I really feel disconnected. Also, the school really discourages siblings on campus at all (teacher has made an exception for the Christmas party as she stated all family members are invited) so for those w/ younger siblings, it can be difficult to volunteer at the school. HOwever, the year I was on bedrest and couldn't be at the school, I volunteered to help the Art teacher. She would send home projects for me to do, and I would send it back with him. For ex: I made the invitations for the Art night (I put them together ie gluing and cutting).
My friend spent time helping the teacher by working individually w/ kids (3rd grade) on poems they were writing for about 2hrs. The teacher was so appreciative, telling her there was no way she'd be able to get it all done, that she hugged my friend as she was leaving!
