我觉得filling diapers是指屙屎吧
While she couldn’t do much, she sure was good at wetting and filling diapers. 这句话是指小宝宝尽管什么都干不了，尿裤子、把尿片弄得满是便便却是拿手好戏
请教wetting and filling diapers是什么意思？
Sister had apointabout the new baby being a stink bug. While she couldn’t do much, she sure was good atwetting and filling diapers.
小熊妹妹说小宝宝是只小臭虫是有道理的。小宝宝自己干不了什么，肯定会常常尿湿自己，要换尿片。
