Yes, for me that's included going away at all. It's the packing, leaving home , travelling , living elsewhere with different people, food, smells, noises and routines that's so upsetting for traumatised children .theonly thing that's slightly better about staying in a home rather than a hotel is that you MIGHT have a littel more control over foods. Otherwise it's just like moving foster homes again, or from their birth famiy to foster care.
If grandparents who live abroad want to see the child, they can always travel to you.
If they are too unwell to travel, then it's probably better for one of the parenst to go and see them and the other remain at home with the children, although that's not ideal. TBH if you have very elderly frail parenst who live abroad and you have to vistsi regularly, then you already have your hands full and probably don't have enough time and space for an adopted child in your life right now
I know this is hard, people always say" of course we will alter our routine to suit an adopted child" but she it comes down to the reality of it, many aren't so keen .
If a child doesn't attach and feel secure , then you are MUCH more likely to have seriously problems later on, especially in teenage years. It's not just that you might have a difficult holiday . It about the child's long term psychological development .
Of course I'm not saying that one holiday will create all these problems. But it's it really much to ask , is it, to have a " staycation " for one or two summers? Anyway , as other have said, you probably won't be able to take the child abroad until the adoption order is granted and then you have to apply for the passport, so that coudl easily be a year or so .
