The case discussed is slightly different from yours, ella. Not all the children were small enough to forget their birth parents and settle down happily with their new adopted parents.
Supposing someone came and made a false accusation against you now, to the effect that you were abusing your adoptive daughter. Suppose it was believed and that you lost your court case. Suppose that your dd was freed for adoption within a fairly short time. Your dd, like the older of the children in the Webster case, would still remember you as her mum, wouldn't she, and quite likely to be desperate to get back to you.
If new evidence emerged and you believed she was still missing you- would you not fight to get her back? Your own beloved adopted dd, the one you have just been to kiss, and who might for all you know be sobbing her heart out for you every evening.
Or do you assume that if your dd was taken away from you now, at her age, that she would just happily forget about you?
I really think the Webster case was a very difficult one, particularly as not all the children were tiny.
My dd was a little older than the oldest Webster child when we had fears of her being taken away. I am absolutely sure that she would not have forgotten us and that, however kind her new adopted parents, she would have been desperate for us to come and take her back.
I think I might go and kiss her now, actually. That kind of protective love is not confined to adoptive parents.
