Angelina Jolie Thinks Kids Are Still Traumatized & Need a Specialist

Angelina Jolie is imploring Brad Pitt to help find a new professional to help them and their children deal with the "trauma" of what happened on their private jet 3 months ago.

Angelina's attorney fired off an email to Brad's legal team on December 1, proposing they "participate in joint sessions with a trauma specialist so that they may learn how to best support and interact with their children."

The request makes it clear -- Jolie thinks the kids are so bad off because of what they witnessed on the plane, and the therapy process they've been going through isn't getting the job done. As we've reported, both sides agreed in September to attend family therapy sessions as part of their temporary custody agreement.

Another sign the situation is still dire -- in docs, Brad's attorney suggested their 2 eldest boys, Maddox and Pax, might not want to visit with their dad.

One source tells us the boys walked out of one session in the past, and have refused to attend others.

It's important to note ... DCFS closed out its investigation after concluding Brad did nothing that warranted official action. DCFS could have referred the case to dependency court if it felt the kids were in danger, or recommended criminal prosecution ... it did neither.

It's unclear if he's responded to Angelina's request.
