Ichi used to say "Poop deta(でた)." when he pooped in his diaper. He combined English word and Japanese word in one sentence. Japanese word 出た(deta) means "came out". I was worried that his daycare teachers wouldn't understand him when he needed a diaper change. But I was also glad that he spoke that way when he said "Mama, poop deta!?" loudly in public.
