DS is 4 and has always been a challenge. He's very strong willed and can be quite the PITA. We've always been really consistent with him and I've pulled out lots of "teacher tools and tricks" to manage his behavior.
The past several months his behavior has really declined and I've gone from thinking that he's a challenge, to--now I'm really concerned it's something more. DH and I have been mulling it over and over and we've decided to get him
an outside evaluation by a psychiatrist. He already gets a full eval through the school district as part of his speech services, but I'm interested to see if the findings match up.
I want the absolute best for my baby and will advocate for him to the best of my ability, but it's so hard and scary to see things in him that I know in my heart and mind are not really ok.

I'm just sad about it and feel like a bad parent that I can't fix him.
Re: Behavioral concerns :(
His behaviors include:
Defiance
Manipulation
Hitting
Kicking
Disrespectful to adults/strangers (one day the cashier at the grocery store smiled and said hi to him when we were checking out and he screamed back at her, "I'm gonna hit you!"...I nearly died).
Talks down about himself-"I'm a bad boy" (we never call him that).
He purposely destroys things and does not care about consequences.
He has zero currency-as in, there is NOTHING that I can use to bargain with him. He doesn't care that much about anything.
This list makes me feel sick to my stomach. Looks so awful.
But, when he's having a good day he is the most warm, mushy, affectionate, loving, thoughtful, funny, silly boy. Just this weekend we were at a BBQ and a little girls' mother asked her if she wanted a cookie and the girl
said yes. DS heard so he went over and picked up a cookie and handed it to her. She said thank you and he said you're welcome and gave her a hug. Some days I'll walk out of my room after getting dressed and he'll say, "Mommy you look beautiful". He's totally juxtaposed. I've been trying to dig and find out if it's something specific that's bothering him and I've come up with nothing.
