The meals you describe are just what they were in my home when I was growing up. The mid-day meal was the main meal, vegetables, salads and meats, and desserts. Then, in the afternoon the youngest kids got got a sandwich and a glass of milk, then baths and to bed. Older kids ate a light cold supper with the parents. Breakfasts were pretty sturdy meals.
All of it changed by the time I was raising my own family -- the main meal became the evening meal, but it took me a long time to accept calling it "supper"! :))
Time to pour coffee and wake up.
