How do you use “whose” and when it appropriate? Like “Whose shirt is this?” “Whose baby is this?” huh???

Whose is a possessive pronoun. Use it when you're asking (or telling) to whom something belongs. For example: whose sandwich is this?

whose is objectifying it, while if you used whom it would be humanizing it.

Whose jacket is this

Whom does this jacket belong to
