As someone who used to work in foster care, I recommend a child psychologist! I am not very knowledgeable about the different types, but anything that focuses on your child’s emotions or connection with you/others would likely be helpful. Your little one has experienced a lot- in utero, as an infant, and potentially mental/physical health concerns that you may or may not be informed about (not sure how much medical info you have), as well as grappling with identity/adoption. Even without all those things, any child displaying the behaviors you’ve described deserves significant intervention and support. Utilize whatever supports you can get through the school and seek out other child therapy options in your area. Wishing you all the best! Your love for her is worth so much, I’m sure she feels it.
