The thing is.. he is so relax. I couldn't believe he is doing fine. I guess I am overreacted about how he will be in school.. Teacher said he cried a little, I think that when he feel restless or a bit scared of something. But the fact he is behaving so well shocked me. Never underestimate your child. They can be so independence at any point of time, and I really need to let go my Clingy Mom syndrome.
