Had better

Had better is used for recommending action or giving advice.

In informal speech, it's usually reduced to ( 'd better) or just better.

3. Question and Negative Question

Because had better is used for recommending action or giving advice, so it's rarely used in Question.
Example:
Had you better go shopping this weekend? (this is rare)

In Negative Questions, we add n't to had.
Example:
Hadn't you better come home? (this is also rare)

Note: We also add n't to had in Negative Tag Questions. Example: You'd better go shopping this weekend, hadn't you?
