independent- the third gift to kid

After 2 years old boy don't listen to me, I start to teach them independent. They still need my help, but when they want do something, I give the freedom and space. I don't care they break the cup or toy. I only hope they study something from  mistake. But I never take the chance from them. Kids are not made of glass. When they drop down, no cry, no help. They will get up by themselves.
