Not really an Aibu but really need perspective and advice.
DD is 11 - in yr 6. She is starting puberty and is overweight (call from school nurse last year repeating that her BMI is in this category). From the back, DD is slim but she does have a large tummy. She has a massive appetite and eats 'normally' - not a good word to use but not fussy, good amount of fruit and veg etc. she walks to school and back (1mile each way) but isn't overly sporty/active. She makes the odd comment about not liking her 'fat tummy/legs'.
Last Thursday I left her for about 30 mins at home when I took DS to a club and came home to find she had eaten the packed lunch supplies for this week. (This included mini snack type bags of scotch eggs, chicken nuggets, cocktail sausages type things). I had got them as a bit of a treat as they were on offer and for convenience cos of my shift pattern this week.
We spoke about it (quite calmly) said I was disappointed by her dishonesty as she had 'taken' them and chatted about healthy/over eating etc. She apologised, said she saw the error of her ways etc.
Today DH is working at home, went to make lunch and reports that the 6 pack of special crisps have all gone. He got them when I was working on Monday. He then found 5 empty packs under her bed! Minx! This has happened before but not to this degree - the odd biscuit etc.
I have decided not to buy any more unhealthy stuff. But I don't know how to deal with this secrecy and her huge appetite. She seems to binge and have no self control. I don't want to make a huge deal of it and give her a complex - Gid knows what the implications may be - but feel I need to guide and support her to make healthy decisions for herself.
