Our SW has said it's not the norm but feels we can cope and we do feel she's absolutely the right match for us on what we've read and the brief glimpse we saw of her on the video call but I'm just really worried about the impact on her and no one else seems to be.
You being able to cope is only part of the picture here though, what do they think of your little ones capacity to cope? I agree that an interim placement with another move planned isn’t really an option, if she has to move the fewer moves there are the better. I also wonder how the male foster carers illness is impacting the atmosphere in the house and the female carers capacity to actually care for the child. It may be that a quick move, while not at all ideal, would be better than leaving her for longer in a home where there are already huge emotional demands being made. I can also really understand the carers wanting to spend time together preparing for his death, if things are as they sound.
If you can spend some time on any kind of intros, I use that getting to know your child, I wouldn’t worry too much about meal times, bed times etc because they are routines that the foster carer can talk you through and write down - the reality is things don’t be the same at your house anyway even if you do follow the same “pattern” because you’re different people and won’t do things in the same way.
See if the sw can press for even a day or two, and use the time for play and interaction, spend time talking about her new home, bring photos, bring a transition object, get to know which toys are precious to her etc.
Wanting to do what’s best for her in such circumstances may be looking at a balance of harm and aiming for what’s least harmful to her, rather than what’s ideal. It’s an awful situation all round, but it sounds like the foster carers are in crisis themselves (rather than just being difficult), and your child might be in a better place being moved from that environment sooner rather than waiting for the usual process to run their course?
Of course, you also have your own, very very quick, adjustment to make which is likely to be tricky. Have sw said what support they’ll be giving in the weeks post placement? We had weekly (initially twice weekly) visits which really helped because I knew at some point I’d be able to speak about my stuff without needing to say I was struggling. Look for sw to commit to decent support for you immediately post placement because you’re little one will need a lot from you, and you can only give that if you’re supported.
