I have two hungry teens at home and there is always fruit and a range of snacks available.
Dd is a sprinter, she has a healthy diet and rarely eats crisps or biscuits. Ds has autism and learning difficulties, he would eat a multipack of crisps in one sitting if he could but if there aren't any he eats fruit.....we go through a lot of apples and bananas!!!
If you have teens / kids do you always buy crisps and biscuits. I've heard people talk about a snack drawer or cupboard but it's never been something I've done.
