Toddler & Night Terrors

Iris came home at 2 1/2 last June, She was escorted to the US. The escort said the first night after the foster mother left she cried herself to sleep pointing at the door and saying MaMa. The next night she was fine, the third night was with us she was fine. About 2 months after she was home she started waking up on her knees pointing. My Husband or I wake her up and hold her and she goes right back to sleep. This would happen about once a week until she saw a spider in her room. then it was about 2 to 3 times a week. Now its back down to once a week. Maria
