Excuse if this is a bit waffled - exhausted, but this is playing on my mind a bit & may not have time to post the question & update replies, before I need to deal with after the School hols ?
It's DDs first over night School trip next year, I've done all the form filling, paid the deposit etc, included covering letter & NHS print out given by her dietician, on which I've highlighted the relevant bits - this wasn't asked for, but thought it easier for them to understand her pretty simple to deal with food intolerances etc - the School are already aware of this - but as its a trip thought giving easy to follow print out would be helpful - I also included a note saying I would update info on a leg injury nearer the time as expect her to be fully recovered by then, but won't know until later due to so potential complication IF she doesn't take things slowly - so figured I'd covered all bases & besides its MONTHS away - Summertime.
Last week I was collared by one of the office staff, demanding that I produce a hospital dieticians letter to back up the info I'd already given 
- this was not mentioned in ANY of the paperwork & I've got to be honest, though I'm usually pretty laid back with most people, this particular woman can get up my nose - she's rude, abrupt & seems to love to over complicate things & IMHO often over steps the mark as regards her role - a bit of a power tripper - IYSWIM -
I protested that I'd already provided a copy of the hospital paperwork, despite nothing in the paperwork asking for it - but was told this wasn't good enough & had to be an actual letter from the hospital dietician - I protested they would expect payment for such a letter (our LHA do) & I wasn't going to be paying when I'd already provided all they needed - she then tells me I should be keeping files on all of DDs hospital appointments & letters & I can just give her a copy of the original letter WTF - who the hell is she to tell me how I should be organising my paperwork 
& there never was such a letter anyway - she kept on insisting I give her the Dieticians name - its was years back & due to my own health problems & DDs deal with various Hospital Doctors & I just couldn't remember
she was very insistent she wanted the letter & name quickly "for insurance purposes" - I left it as "I'll look into it, but its not top of my list of priorities right now as the trip is 8 month away & I've Xmas to deal with" - she also demanded a copy of DDs physio treatment plan WTF
DH picks DD up the following day & she collars him & demands the letter I'm meant to have given him for her
I've had other minor run ins with her - where she comes across as very disbelieving of DDs problems & obviously thinks I'm just fussing & wrapping her in cotton wool - trust me, nothing could be further from the truth - we just happen to have been unlucky & DD does have a habit of getting things that are "not normal" 
AIBU in thinking this woman is just making things difficult again & on a power trip,
OR as its our first experience of School trips - is it normal procedure to be expected to produce realms of medical letters for an over night School trip - for a child whose problems aren't life threatening??
TIA :)
