Re: P.T.S.D in a 4yr old?
i think that you should tak as much as possible to your niece when you get a chance - you should not let her keep inside what she feels about past events.
Maybe you can become a better counselor for her.
Or at least you can get her trust to the extend that she should come and tell you anytime about anything that bothers her.
She needs to feel completely safe somehow and somewhere to open and you can create that zone for her probably.
