True meaning of brother and sisters

We often heard story about how brothers and sisters jealous of each other and each one of them fighting for their parent attentions or approval. Most of the time, the bigger sister will bully her younger siblings. Some terrible stories including how the big sister pulling the brother's "bird" (yes, that bird haha), kicking him off the bed, biting him and pulling his ears (yes, like a little devil esp when they are left alone together), bla bla...etc.

So, before Zhuo Yhing was born, we did discussed about this issue and we agreed to take some precaution eg not to say anything that can cause any distress to any one of them. Especially that the bigger sister can understand what we say. We also made pact to love two of them and not side either one. But, now it turns out the worries is just worries. 

Yen Yi love her brother very much. 

I would hope this situation will continue indefinitely.
