Congratulations Applewisp!
I think my (donor egg) daughter doesn't look much like me, apart from eye colour, but friends who've only known me as an adult think she looks like me. I think mannerisms plus people's own expectations fill the gap.
Some women I've been friends with since school have children who look so much like the younger versions of them I can still remember. Same with my nieces and nephews looking so like my siblings, they remind me so much of my own childhood.
My daughter does look like her dad in some ways, she has his genes and probably a mix of our two personalities.
All I know about the donor is her age and blood group, I had treatment in Spain.
@oldeggs I don't know if you have moved forward with donor eggs. Here in Spain (and I think in many other places) they place so much importance on getting a donor who resembles you, to try to have a child who looks like you. Well, in the end, a child can look like their genetic parents to a greater or lesser degree. I look very different to my siblings.
I think epigenetics is not going to make a child you carry look like you, but if you are fortunate enough for treatment to work in time I hope you realise that is not important at all - yes, grieve the lack of genetic connection, preferably prior to becoming pregnant. But what you can end up with is pretty special.
