@Sakura7 I know, but it's a sensitive issue. I know better than most about this, because I grew up with my F's Parkinson's Disease hanging over us. And my DM was orphaned at 10, her F was 82 and her DM 49, dying of a heart attack.
My paternal DGF died in the war, shot by the Gestapo (my F was Czech). My paternal DGM died at 70 of a heart attack, as did my F, of septicaemia, when in hospital having had a major stroke. (He was no loss as he had abused us when we were children.). My DM is the only one still alive at 80.
Life sucks sometimes. So I do get what you're saying, but sometimes life doesn't work the way you want it to.
I do think adoption is different as I didn't go through a risky pregnancy, like my DSis did at 38, nearly dying of pre-Enclampsia, and also had gestational diabetes. She then went through it again 2 years later. I kept my mouth shut but I was very worried. I suspect they adopted their third child, their DS, because her DH put his foot down. There's a 22 year old DSS and 2 small DC too. They're wonderful parents, but what she did was very risky.
Adoptive parents have always been older than birth parents because usually they TTC, go through IVF and then are expected to take time to come to terms with infertility and then a lengthy adoption process. It's not right, but, ask yourself this; if we hadn't adopted our DDs, who would? There aren't any couples of the 25-28 age applying to adopt (or very few).
