We had similar with out 9month old AD. FC were an hour away, winter time, 6am start (because LO woke at that time) and didn't leave until after 7pm (LO bed time) every day plus BC back at home missing us desperately which meant that often we would drive separately (we negotiated this at planning meeting.). There was no budget for hotel but also not practical as BC at home.
. It's very hard, intense, exhausting, but we did it. And although it seemed bonkers at the time, I think I cried when I read the schedule, I could afterwards see their rationale for doing it that way. Hopefully it will make more sense when you're in the midst of it.
You will be able to report back to your SW every day. There was a point when I felt very strongly that despite me being the "main carer" (and therefore the main person who should be doing all mornings, bed times etc) our BC needed me to go home and do bed time with her. SW agreed and DH did bed time instead.
It's ok to voice any concerns you have. It's also OK for you to ask them to explain why the Introductions are planned this way, it may help you to feel more on board with the schedule.
You'll have a mid way meeting where again you will be able to discuss any difficulties you are having.
We were absolutely knackered and fell into bed every night.
Stock up your freezer with meals, get takeaways, tell friends and family that you're unlikely to be in contact much so not to call or expect updates.
And make sure you know in advance what food to have in for LO when they come home as you probably won't get a chance to go shopping between introductions and bringing them home..
It's a mad experience but also wonderful amazing and special. Ask FC to take loads of photos
and congratulations
