我個經常尿床尿到三年級,打後就間唔中,快15崴啦,上兩個月都試過,但尿醒左,急急去廁所呵,也整濕床單少許.慣了.小時己看過醫生,檢查話冇問題,醫生重話如果有d人尿床至14歲,係常小小常果隻,到時再檢,因為人的机能發育程度不同,晚上8時後不喝水,父母辛苦d,夜d目訓,叫佢起身去廁所,一定不能責罵,另外我自己覺得做父母都唔好成日提起,更加唔同d多口多意sorry something wrong with my computer so I got to type my poor english. Please don't talk to much with others this might hurt your son. I just treat as one of my housework only. Of course, sometimes you should encourage him when for example he doesn't pu pu at nigtht may be within a week. Another thing is you should make sure there are no others reasons such as having problem in school or sometime you wanted him to be (good result....) and that he can't fullfill your hope. Support is a very important way.So please be patient and hope you can succeed. And once again it is so long to bother you.
