"When you were a baby did you do 돌잔치 ceremony?" 1. 아기(셨을) 적에 돌잔치 했어요 [하셨어요]? (textbook-like and somewhat stiff sounding. 하셨어요 is more formal) 2. 아기 적에 돌잔치 했더랬어요 [하셨더랬어요]? (what people are more likely to say) 하셨어요? ending sounds a bit too serious as if the the asker wants to know it in earnest. Since it is not such a serious subject, the -더랬어요? ending is more natural. -더라(present), and -더랬어 have the feel of asking about or relating one's experience casually without sounding too serious and formal.

It didn't have Korean as an option. Idk why.

Add Korean to the languages you're learning under Edit Profile and then it will show up as an option.
