Hi Jeni, welcome to the forums 🙂
As a family, we (myself, my wife and my 2 year old) all eat pretty much the same thing - I just alter some of the quantities and swap a few things around.
Generally in the evening we are very much a meat and two veg family, I'll generally have less potatoes and more caultiflower/brocolli/etc but it's still the same things on my plate as everyone else.
Most meats don't affect blood sugar too much and if we eat things like breaded chicken or fishfingers, I just remove the breaded bit if I'm concerned.
The only real exception is for puddings where I completely avoid the cakes when we have them.
