My son has free access to all snacks for him to help himself. Fruit, crisps, crackers, cheese, etc. And do you know what Joe? He goes for a snack when hes hungry and still eats his meals. Healthy meals aswell. Today he had mixed bean and roasted pepper chilli and ate the lot. only 45 mins before tea he had helped himself to an apple. He isn't usually constantly in his snacks, because I believe in teaching how to self regulate and that's something he has learned to do. Sometimes if he wants a snack not long after lunch, I offer a cup of milk instead and he is usually satisfied with that.
Teaching indie to starve herself in between meals IS NOT healthy. It's not something the majority of adults do, and definitely not what children do. Why do you think milk and fruit is offered as a snack in primary schools? Because they need to be fueled to function. No matter how many bleeping eggs, oats and chia seeds you feed indie, it is not healthy when you are teaching her UNHEALTHY habits.
Why would you not even try your child with a cheese sandwich, carrot and cucumber sticks with hummus and some fruit on the side. Theres more to life than superfoods. LET HER BE A CHILD!!!
