ooh Pooh" nearly 10 times until Sat afternoon. He is very serious. When he consulted the doc on Sat afternoon, the doctor said there are many children suffered in such cases recently. Actully, he recovered by himself, he cannot take the medicine, once he take the the one for stop vomitting, then he would immediately vomit. So I cannot feed he the medicine again. Luckily, he got only 2 times of "pooh pooh" yesterday. so today I let him go school. Up to now, no more vomit & "pooh pooh". But he feels no appetite to eat. I let him eat plain congnee only. I questioned Lok Lok any child vomit in the school on Fri, he said no. I think he may eat some dirty food.
