奶樽同食完既飯碟放埋一齊, 好污糟; <-- this one you can tell her to change
d野食唔放入雪櫃, 就咁放microwave幾個鐘; <-- this one you can tell her to change
有次見到佢將飯同生肉一齊蒸俾呀仔食 (最後都係熟晒既); <-- I think this is ok....?
食完飯睇報紙唔立刻洗碗; (但我覺得總之最後做完就得啦) <-- like you said .. as long as she can finish la
"有心機教我呀b" <-- this is very hard to get ... and BB should come first... think better to keep her
