Hi, We are still going through our

Hi,
We are still going through our adoption assessment. Hoping to go to panel in March/April time.
I am looking for some guidance or advice from yourselves or any recommended reading. My DH and I have a close extended family on both sides which is wonderful. My sister's partner is my brother in-law and they had a beautiful baby boy last week. I am a very proud aunty and I was with my sister for the birth. My nephew is the first grandson on my side of the family. It has brought back some grief for my DH and I, which we did expect. I am also asking myself so many questions on how we are going to introduce our adopted child to the extended family as it is going to be so different to how my nephew is being celebrated. I am already worrying for my child. How is my child going to feel when my nephew is likely to get told how much he looks like his Dad. I know I am jumping ahead with this. Part of me feels like moving away however we need our family and our child will have wonderful cousins to grow up with.
Does anyone have any advise on this or recommended reading? I have so much and so many emotions running around my head at the moment.
Thank you
