✔ 最佳答案
有錯
[with] is used before noun / pronoun
你可以話 "I help him with his homework"
但唔可以話 "help him with doing his homework"
所以你o既句子唔應該用[with]
I help him with looking after his child. 可改為:
I look after his child for him.
不過如果你一定要用[help], 都可以改成:
I help him (to) look after his child. *[to] 係可有可無
但你唔可以改成
I help him looking after his child.
不過有種習語係可以 help + verb(ing):
cannot help (doing) sth = cannot avoid/prevent sth
