I think the Ansh Arti equation is perfect. I have a 4.5 year old but he behaves like at least a 6 year old. Thats exactly the way I am with him. The arti doing gussa to Yash for not explaining to Ansh nicely is a common senario with us. Sometimes if he misbehaves I find a reason to yell at Daddy also and put them both in time out together. This gives my husband the opportunity to explain my lil one his faults as an insider who is in trouble as well. Then they both look towards me and come and say sorry and that they will never misbehave again. This works beautifully for us. Plus my son never feels like he is being put on the spot or being punished alone and yet the disciplining comes across.
The point is to discipline the child and not have a upper hand or ego battle. So I think for me Arti's way of dealing with Ansh is perfect. Its not Anshs fault that he's in a house full of strangers who have different expectations from him.
