Loving and fighting with Charmaine

I guess that is children, especially when they are young, they play together, fight, but many of times too, they love and care each other. There were times, she came near to her sister who was sitting on toilet seat doing her wee wee, grabbed her hands and kissed her and kissed her all over. She would say Charmaine so cute........If I said Charmaine is little pussy crocodille, Beth would say ...I am cece crocodille. But if I said, ou..ouh.....can't be like that, if not mummy will say....round in the garden, looking for anchang/dirty/naughty/cranky bethanie, she was not happy, and she then would behave well. Sometimes, she would give in to her sister too, Charmaine always wants to win over everything. She is jealous over her sister all the times. But there are times, they fight and bite each other. If mummy and daddy scolded her sister, Beth would say....No, daddy, don't scold Charmaine, or don't beat Charmaine. I sayang you (her sister).
