I find this so hard.
With DDs who aren't far from teenage years I'm finding this a tricky balance.
Currently DDs are healthy and happy and have a good diet. Naturally slim builds so will occasionally get called skinny but DH is 6'4" and 12 stone and none of his family gain weight on their arms and legs so it's just in their genetics to have that sort of "lanky" look.
I reassure them they're healthy weights and have strong bodies (as they're aware from their gymnastics/swimming)
But.
In my early teens I piled weight on. I went from a reasonably skinny kid to a chubby teen. Looking back it's not much of a surprise as food wasn't great quality (very 90s)
Equally my mum and grandma were diet/weight obsessed and never stopped about weight loss/diets so I could tell that to them me being a size 14/16 was horrendous. Lots of talk about what I ate etc. (I've since gotten a lot healthier now a size 10/12 but don't make a huge deal of avoiding food etc just that I don't snack)
So of course I'm VERY aware of how I talk to my DDs in regards to food.
But where is the line between not making a big deal of food/body shape and encouraging healthy lifestyles.
For example yesterday they were hot when we got in from school so had an ice lolly each.
Then an hour later we popped into MILs and she offered the kids an ice cream. They said they'd already had a lolly and looked at me and I said they were right that they'd already had a sugary snack and it wasn't long until dinner.
MIL acted as if stopping them from having the ice cream was cruel of me. And I can tell she thinks I'm going to force them into eating disorders.
Sort of feel like I can't do right for doing wrong with them.
