DS is v small at school nursery 3.5, but I have range of pitta/biscuits/cake but he really likes carrot or banana cake, which I feel better about. I have to have snacks in the playground as he can't wait to get home. Can't make either carrot or banana cake, actually can't bake at all, so buy one from local farmers market poncery, cut into slices freeze individually and take out the same morning. Loves that.
