My daughter, age 4 and 3/4 is still up at 1:06 a.m without taking a nap all day long and has madrasah in the morning at 10 a.m that she has to wake up for. Why is she up so late you ask? Well my cousin, age 10 is over and the two of them are talking. Actually she is talking to her and the other one is listening. I'm not much of talkative person so I have no clue where she gets it from.
She has a bad habit of correcting her brother's every move. Its actually irritating. He is not allowed to make mistakes in front of her. Even the way he cries or laughs.
