For my 3 children when they reached 12months old then I stopped the breasfeeding. But still we had a supply of powder instant milk in big tins that was recommended by their pediatrician.
Because we are 8 siblings, this is what my mother taught us and she said: "start giving your kid/s the real foods like soup from all the green, leafy, yellow & vegetables particularly mashed potatoes & carrots w/ shredded chicken meat in it." After each meal they had fruits. (bananas, papayas,oranges) grown & bought from local farmers during that time.
