For some reason, JE refers to SE as 'it'. Reporting to me, "It was walking-walking, then suddenly, it fell down" or 'It is so naughty, it bite me!". Going to tell kakak that the sister has woken up and is crying. "Kakak, it wake up already! It is crying!"
I tell her that it should be 'she' because SE is a girl. But half-heartedly for now since I think 'it' is quite cute!
