'she and your dh expect you to do the lion's share of the childcare, which has a strong emotional component as well as physical'
This is true. The emotional impact on the dsd will be huge I am sure. Should Tess shoulder this? Can she even if she wanted to?
It has taken many hard years for me to come to terms with the circumstances of my adoption and abandonement. The impact of my firstborn was overwhelming and I was 27 and married. I had a supportive dh, ILs, friends and counselling. This girl has a huge journey to travel Tess and you cannot be expected to provide all she needs.
Does the dsd have any other relatives? Aunts/uncles/cousins? Grandparents?
I think the father and his parents should be informed asap and be part of this process.
It does depend on the parents of course but if it was my ds, I would want to maintain contact and support/help where I could.
This is not all Tess' responsibility but it seems to me that she is being the huge rock everyone is leaning on at a cost to her own well being. Sorry if I am stating the obvious, just a bit slow catching up with the thread
