Hannelore,
My birth mom abandoned me when I was 25 months old. Little people may not remember particulars, as your DIL claims. But from one that knows, when a person is very young, trauma can be difficult to overcome. Ana needs love, hugs and kisses and more love. I deeply respect and fondly recall those folks' that loved me when my biological family simply disappeared. My heart goes out to you and Anaiya.
Prayers and blessings...
