By noon, "Umar, adik is having her lunch. do you want to have lunch with her?", I asked him. He's still young, and this is his first attempt in fasting...I thought he might want to break fast by noon. (moreover, I did not wake him up during sahur). "No, I'll eat when you eat".
By late afternoon, "Mama, can I have a taste of what adik is having? Just a little, tiny miny. i don't want to break fast yet, I just want to have a taste." After a long explaination to him, he break fast at 3pm. I think that's good enough for a five year-old. I didn't expect him to last later than lunch, to begin with.
