I've always encouraged Arzu & Kabir to share everything they have and so far it going all good. But, this morning Kabir wanted to brush my teeth with his toothbrush. I think he took sharing too seriously 😁
It's tough to make toddlers understand what to share what not.
For now, I think it's better to just let them get used to a good habit. I am sure with time they will learn more on it.
