Yogurt lover

No doubt Ethan loves eating yogurt. When he saw his mother takes out the yogurt from fridge during his meal time, he will give lot of excuses not to eat rice like stomach full already, the food is not good etc. After mother gave him the green light that he can stop having his meal, he immediately went to pick the yogurt. Then mother will tease him by saying:" I thought you are already full, are you sure you still got place for the yogurt?". This fellow he just ignored mother and enjoyed his yogurt.

Mother doesn't know why he loves yogurt so much even though mother tastes and felt they are a bit sour for mother. Don't know is it because mother had a lot of yogurt when Ethan was still inside mother's stomach. Last time mother had one bottle everyday because was afraid of the yeast infection during the deliver. But seems like a lot of habit mother had during the pregnancy have been passed down to Ethan for example he loves to drink milk.
