Which research stopping? Hospital or attachment? Having had a child spend almost 3 years as a long term hospital patient mostly with me or another family member with her where possible obviously I think this is a good thing, attachment wise I always think learning more and paying attention to what is already known is a good thing.
And no I didn't say we should ignore all reserch. What I said was not that much different to what shakshuka said.
That being for some children indirect contact would be in their best interests for others it would not be. I did expand on that by saying something along the lines of that the person often based placed to make that decision (assuming no abuse fears or history of drama llama behaviour) is the trustworthy parent with the child.
I quite agree that often the children who appear less effected by trauma are the ones where more care should be taken, I also think that being low or withdrawn can often be a bigger indicator of distress than weeping and wailing, and I do think it's a bit questionable to not spend a significant amount of time preparing children for absences in age appropreate ways prior to that absence happening when it is possible to do so because you have just assumed that because they are children they are adaptable and no support should be required.
I also don't think it's become a silly buzz word at least no more than "wishes and feelings" have.
My understanding is that if a child is saying no I don't want to talk to mum/dad inbetween normal contact because they cannot cope with it,the current practise is to work on that in the long term offering support with their emotions and relationships whilst respecting their wishes and feelings in the short term with the possibility of a less in your face way of getting the I love and miss you message across so the child can digest that on their own terms if it is age appropreate to do so.
The op is talking about a 3 and a 4 yo, I know a lot of children that age would struggle quite a bit with the entire concept of telephone calls or Skype obviously there will also be a lot that won't but some will also love it (I have a 2yo who thinks it's fantastic) and some will hate it (I have a 3yo who is totally freaked out by it).
We also don't know if any distress was contributed towards by how the conversation occured sometimes many adults without even realising it can ramp up distress due to their own distress the best intentions are there but the contact can be emotionally damaging.
Yes I do have a lot of faith in the system ,I've not known that system to blindly follow a party line (but on occasion just recently it looks like it's going that way) and of course that system brings into it a great many experts usually ones who have been asked to use their expertise and the relivant reserch to comment on a specific child or case, I'm surprised you don't know this I thought most people did.
