I mean learning is always baby to baby really, there might be an average but an average takes the most and least and finds the middle so it’s a weird one. In our baby’s case here, the English has her going daaaa for her daddy and then she says papa in the end. But in the Korean version the daa is actually “appaaaaaa” which is daddy so she is able to say a two syllable word, but our top asks him to say Abbuji which is a more complex word with three syllables, with the the english counterpart being translated as papa” and our baby does manage to say “abbjii” changing it to a two syllable but it’s still pretty good.
it really just depends on the baby’s development. some don’t talk until three or four years old, but they show they are intelligent in other ways
At seven months shouldn't she be able to say a couple of words already? I know babies have an average of couple of months between development landmarks but my niece was able to say mama, papa, manana(banana), titi (should be "titia", portuguese for "aunty"), auau (what we say in portuguese to be the sound off dog bark) and a couple more I can't remember now. So maybe korean is harder to recognise baby noise as words? Or my nice started too soon? （￣へ￣）
