我儿子20个月时开始上托班,身体发育良好,已经学会自己解大小便了。到了3岁10个月,儿子转学至另一所幼儿园。头两三天,一切正常,回家后他还兴奋地和我们谈起新幼儿园的许多新玩具和新朋友。第四天下午,我去接他时,发现他把大便拉在裤子里了。从那天起直到现在,一年的时间里,他有十多次把大便 When my son started attending classes at 20 months, he developed well and learned to relieve himself. By the age of 3 and 10 months, my son transfers to another kindergarten. For the first two or three days, everything was fine. After returning home, he was excited to talk with us about many new toys and new friends in the new kindergarten. On the fourth afternoon, when I picked him up, I found him pulling his stool in his pants. From that day until now, he has given the stool more than a dozen times a year
