Not quite an adoption story but of a similar vein.
Due to unfortunate circumstances, I have parental responsibility for my two grandsons. They have been with me now for over 4 years. Both needed a lot of security and the comfort of a stable home.
They see their Father often but in the beginning they missed their Mother (my Daughter) very much and had lots of questions.
I was able to show lots of photographs and explain first hand how much she loved them both. We built up a great relationship between us all and in between the tears, the heartbreak and confusion etc have adjusted to life.
The idea of a life book/scrap book etc is very positive.
