I don't care if I'm seen as a busybody particularly but I would be interested to know how people view parents who help in school.
I was a parent governor for about 12 years while my older children were at the school, I was also on the PTA during that time and built up good relationships with the teachers and headteacher. I was very careful not to use my position as a governor to further my kids' needs and have several times voted for things that benefit the school as a whole while not being what I would choose for my own child etc.
Since DS3 started at the school I have started going in to read with children in KS1 - I told the head when I stood down from the governing body that I wanted to stay involved and she suggested I go in and read - I did a 2 day training course on a reading intervention program and do that with a couple of children and normal reading with other children. This involves me being in school three afternoons a week. I also do a couple of shifts at the after-school club each week (paid) and emergency cover for the dinnerladies (also paid). I have been asked to accompany various classes on trips too. I see what I do as supporting the school as a whole and have no direct involvement with my own child at school though some of the reading is with children in his class and occasionally his teacher will chat briefly about him while I'm there.
Would I be seen as a busybody? A mug? I get the impression on MN that mums who are in school quite a bit and go on trips etc are not seen in the best light.
