I strongly recommend looking into neuro reorganization (NR). Bette Lamont would be an excellent practitioner.
We adopted our daughter at 4 1/2 from the Ukraine. She spent her life in the orphanage and had significant delays due to her environment, including all of the ones listed in your post. We tried all types of therapies and although they helped a little, 5 years later we had only made limited progress. We finally found NR. We have only been doing NR for 6 months and she has made TREMENDOUS progress! Our friends and relatives that don’t see her on a daily basis say she is a completely different child! We still have much work to do but it is so exciting to see so much progress in only 6 months! I really encourage you to contact Bette Lamont.
