I am trying to order my thoughts and I'm confused by this.
Sometimes, DD2 will show a little empathy. For example, if I say something self-deprecating such as 'Sorry about that, I'm a terrible mother...', she will say 'No you're not! You're the best Mum in the whole world...'
But generally, she just doesn't seem to get it at all. Today, DD1 fell a full flight of stairs, top to bottom, hitting a small suitcase on the way down, then crashing into a wall (at BIL/SIL's house).
DD1's cousin made her a playdough smiley face to cheer her up. DD3 approached us and cuddled DD1 tenderly. DD2 carried on regardless. When I finally said 'DD2, DD1 has really hurt herself', she just shrugged her shoulders and said 'I know.' then carried on doing what she was doing.
It seems so cold. I tell myself that she must not realise, but I don't think I really understand why. I don't understand why she doesn't show empathy towards people unless there is a very obvious 'this is what you should do in this situation.'
