There are a million reasons why this is different from a ‘normal’ dad-kills-baby type situation. (I’m struggling to believe I write that sentence, tbh.)
One of them is that instead of getting a lovely immobile newborn, you are given an angry, terrified, grieving infant, who won’t in all likelihood respond like other infants do and for whom normal parenting won’t work. It’s also one of adoption’s big taboos that you don’t love your children from Day 1. And obviously if you’ve got a child who is traumatised/‘difficult’/different then that bond may take a long time.
The second difference is that he had been ‘vetted’ and ‘trained’. This means he should have known that the child would be traumatised/grieving/different etc and that he was judged to be able to cope with this. One of the things SS say they look for is your ability to ask for support when it’s needed. He obviously wasn’t able (or chose not to).
And honestly, the ‘training’ we received was pitiful. Woefully inadequate. We were very ill-prepared. And no-one gives a shit normally. How we got through the early days I’ll never know (and by early days I mean first year.)
Thirdly, before the adoption order was granted, he, unlike birth parents, had the option to say ‘I can’t do this’ and disrupt the placement, literally, to hand the baby back. But he didn’t.
And fourthly, before the order was granted, Elsie was still a looked after child. SS should have known about her injuries. But in an adoptive placement that normally means one visit every few weeks.
There are a lot of questions for SS to answer, and not only about how he ‘slipped through the net’.
