NC’d for this.
I have 3 girls, one of secondary school age and 2 still at primary. Very active and busy kids and all 3 are naturally quite slim and healthy!
We like our food and both myself and husband are good cooks and the DC have a balanced diet with plenty of variety, we are also pretty normal in terms of snacks and I have never been too precious about them having a packet of crisps after school or the occasional can of lemonade and it’s never previously been an issue moderating what they eat.
They do come and ask if they want something out the treat cupboard or fridge (toast and fruit is for a free for all) I know this isn’t a very popular parenting choice but I’m paranoid about their teeth and it’s also bloody expensive making sure there is enough there for the week without them digging into all the school snacks.
Over the last 6 months the youngest two have started sneaking food, eating and stashing the rubbish, this isn’t just the extra chocolate biscuit but packs and packs of biscuit, breadsticks, crisps, chocolate, cake, anything really that they can get their hands on! sometimes it’s when we are not looking during the day but other times (and I find quite worrying) it’s first thing in the morning before we get or after we have all gone to bed, it’s starting to feel quite secretive/bingey which I’m petrified is going to turn into an eating disorder.
I have been so careful about how I’m handling it as obviously don’t want to food shame them but this morning I came down and read the riot act (fuelled mainly by the fact that we are pretty skint this month and I had carefully worked and bought out how much we needed for the next few weeks) after finding 2 empty boxes of cereal bars, and an empty bag of fruit flakes and two innocent little faces looking at me saying “It wasn’t me!!” I think the the lying was the final straw!
So much so my youngest has gone to school without a lunch because I told her she wasn’t getting the previous included chocolate biscuit to which she replied “fine I won’t eat my lunch” to which I replied “fine it saves me making it!!” Not my proudest parenting moment and a 1st for me but the whole situation is making me quite sad and stressed.
I don’t think it’s necessarily the amount of food they are consuming, obviously it’s not great but I also know it’s kid like to want to eat lots of treats but I’m worried about the behaviours along side it, the lying, binging, hiding, even me having to ask them to constantly stop doing it, however understanding I have been in the past, It doesn’t sit right with me to constantly checking and judging their food choices which I’m still doing, albeit for the right intentions.
I just wondered if anyone had any advice or has had similar with their own DC and how we handled it. DH is a lot firmed than me and has said we either stop buying it (which I don’t think is fair on my eldest DD or me!!! 
) or we get a lock for the kitchen door but again I’m worried that this is just another from of food shaming!
