Every time I read about her children behaving like that…. I’m reminded of my 15mo son who was already walking but can’t speak properly yet and sometimes he doesn’t understand what adults are saying…and it’s normal irl Her children can speak very well like 3yo … and they can understand what adults are saying, can walking properly even can running….even though they are not reached 1yo ..WOW and YES It can happened in the novel 😌
