[Grammar] Help him do or help him doing

[Checkmate]

"His mom helps him doing the homework" is fine.

'Helps him doing' is not correct.
It should be 'helps him do(infinitive)'.
'Helps' implies having a part in doing the home work.
Better to say: His mom guides him with/in his homework.

It's just a post about whether to use "help me to do" or "help me do"

As the dictionary says 'help somebody (to) do something', we should simply follow it rather than try to devise a different usage.

Are there any other word exclusively used with infinitive or gerund only?

Why is the infinitive [strike]is[/strike] used instead of the gerund?

Checkmate, don't forget to use the correct word order for questions, and to use articles when they are needed.
