Awesome job with urself and the kids! I wish my mom went that route--changing from junk food to healthier options when I was a teen. Instead she put my on diet pills and crash diets at 13 even though I was maybe 10lbs overweight.
I buy "healthier" junk if you want to call that for my kids--100 cal packs, baked snacks, and lots of fruit--sometimes in a parfait with yogurt... Plus I sneak veggies and sometimes benefiber into their food to up the health factor.
I think it's so great that you are doing this. Your kids will thank you one day if they haven't already
