Thanks for all the responses. They are definitely food for thought. The restricted diet has been ongoing from around 9 months old. She eats beige food, predominantly, but will eat raw carrots and cucumber. She eats apples, melon, raspberries and has fruit every day. Also peppers. I looked at getting help for her diet and there was a list of foods to check against. She had around 21 different foods she would eat, which put her over the limit for help. She eats plenty, but not a wide variety. School lunch is generally dry French bread, an apple and a chocolate brownie. She has rice krispies and milk for breakfast. Chips or dry pasta for tea, gammon or chicken or goats cheese. No sauces, limited variety. I don't flag this as an issue because it's her life. I have tried to address it numerous times on this forum and with the GP but get told either 'it's not as bad as you think' or 'you've caused this problem by being indulgent' and 'starve her...that'll sort her out'. I don't really think the food issue is overly to blame, apart from the fact that her lunches at school are cause for worry. Will be trying hard to encourage her to do packed lunch and multi-vits.
Monday/Tuesday/Wednesday she currently doesn't do any activities. She did do football, but the sessions are off and on depending on the teacher and their inclination to do them. She is usually in bed for 8.30pm and the lights are off between 9 and 9.30pm. She reads before bed, but sometimes does have trouble sleeping. No gadgets in the bedroom.
I've double/triple checked about concerns. We just had her birthday party and she has a fab bunch of friends. They call themselves the library nerds. She embraces her nerdery and her friends equally. She is strong, so doesn't take any nonsense from anyone.
She has piano on a Thursday evening and doesn't like it, so I'm guessing that may be having an effect on Thursdays.
When she's off sick, she's a couch potato. She'll watch tv and read but is happy to stay scrunched up on the sofa with a blanket. I do think it's a little bit of laziness.
She is moody, but we are generally quite open about issues. She hates some lessons, but not overly. She has recently fallen out with someone at school, but she says she isn't bothered about it. She doesn't like the person and is stuck with her and she puts up with her. She's philosophical about things.
She's private, so she wouldn't necessarily tell me everything but I do think (hope) she would tell me if there were problems. She has seemed happier generally. I think it's psychological and I think she's trying it on a bit. I suspect she feels a bit off, maybe with body changing, but isn't so ill she needs to work. Being a part time worker, I've been able to sort out most of her off days/early days. But today I explained that if she's ill this frequently, she needs to see a doctor. That if she has time off it will have implications. That if she is so ill, school will let me know.
I really appreciate the feedback and am sorry for the war and peace response, but I wanted to answer everyone as I really appreciate the feedback and it may make someone say 'ah, it's clearly this'. I am perhaps too close and too precious with her, though I try really hard not to be! It's only been going on for 6 weeks and part of me thinks I need to wait and see if it improves with a toughened up attitude. If not, if I get a call from school again today, it's definitely time for a chat with school and the doctors. Thanks again for the responses.
