"Grand so" is an Irish English phrase meaning "fine, then" or "okay then." Conversational agreement marker. Not concerning, just Irish vocabulary. If your kid uses it constantly, ask them where they first heard it, not to police their speech but to understand which online community they are in. Most slang of this kind moves through TikTok and group chats, so seeing it in your child's vocabulary just means they are plugged into normal teen internet culture.

For ESL learners
Grand so is a fixed Irish English phrase meaning "that's fine then" or "all right then," used to close a conversation or accept a plan. Use only in Irish English contexts. Formal equivalents: "fine," "all right then." Common non-native mistake: separating into "grand" + "so" semantically; in Irish it functions as a single agreement phrase. "So" here is a discourse particle, not a logical connector.

“Whereas, if it were me, I’d probably buy something like a Steinway Model D grand so I can really get serious about piano.”
