I'm not a mom, and I'm not an expert by any means, but I have mentored some younger kids that have been through some tough times, and it sounds like it certainly couldn't hurt to have Tali see somebody. She could even do Play Therapy--basically, go in with a therapist, and "play" out her feelings, a method that I've seen have great success in younger kids, without causing them any sort of trauma or really bringing bad feelings to the forefront. It's amazing how a child's psyche can resolve things without really facing them (whereas we, as adults, sit and stew over them day in and day out).
You might want to check around and see if you can find a child psychologist that does play therapy. I know it's used extensively in younger children who aren't really able to talk about feelings, but with Tali, drawing pictures and playing house with dolls might be a useful way to work out feelings.
Hope this helps some. I'm so sorry for your loss.
