no worries... slow start does not determine how they can talk in future... mine started super late but now super talkative after 3yo
Don't worry. My younger child started to talk at 3 years old and is so talkative now. Prior to that, she only knows papa and mama.

some baby takes longer time just wait awhile and see how it goes
