Aibu to be concerned about my daughter?

[Barbaquequeen]

My daughter is10years old and is of a slim build. She enjoys 3 different sporting activities but outside of this she does not play and run about in her spare time as she used to. She much prefers sitting on the couch, watching tv and has to be coaxed to play out.
i hVe noticed she has started to behave in a sneaky manner when it comes to food. She will take bars from the treat press and take it to her room. She returned home from an activity late last night and I asked her would she like to get herself a snack before bed. She buttered no less than 8 cream crackers. I said nothing as I didn’t want to make a big deal or an issue out of it and I didn’t want to make her feel bad or ashamed. I try to make her have a good attitude to food. She has 3 good family meals a day, I will always offer her more at these meals and she is usually given a treat or desert daily
should I have said something about the cream crackers and should I be concerned?

There’s no pattern of behaviour that’s alarming.

Leave her be.

Maybe she's 'sneaking' stuff as she so obviously senses or sees your disapproval.

As others have said she's probably growing or about to be. I was tall and slim and then bang at 11 I grew to my full adult height and stopped!

Sounds like you need to have a think about what nice healthy stuff you can provide for her to eat especially after activities. Something like toast and hummus, fruit or carrots, even cheese on toast or tuna. And yeah the odd cream cracker isn't going to do her any harm.
