AllTheMadmen the using of children has been common for a while, but the cases I've seen have mostly been West African - if it became a criterion, though, I bet it would become a whole lot more common: there's already a big problem with child trafficking and enslavement (and Britain, sadly, is the human slavery capital of Europe) and I could forsee issues round vulnerable parents being exploited, and told their child is going to be resettled into the UK etc and being a gateway for the parents, whereas in fact, it's the same old story- the child will be exploited, possibly through being sold to richer claimants in Europe, and the parents will never see them again. At the moment, in some cases, parents are given a payment for the child (and told it's for fees to get them established in their new life as a nanny/in school etc) - this could potentially lead to the criminals extorting two sets of money for the same child.
I am very much in favour of resettling people from camps, rather than from mainland Europe. However, I am also conflicted about that, in that essentially, someone who is taken from a refugee camp and resettled in a third country will statistically never go "home". It's not that I am saying we shouldn't welcome people here - of course we should, and if it's their choice to stay once things are safe at "home" then of course, they are welcome to. But there are really big implications, over and above those of individual families, to this policy. Essentially, if we aren't careful, we could end up doing ISIS' work for them, leaving a Middle East devoid of Christian sects who've been there for 2000 years, not to mention Yezidis, and the potential for this to spread also to other sects, including the Druze and the Alawites.
I support strongly the government's policy of extensive funding of the camps - we are the biggest donor after the US in this respect - but at the same time, there's not enough money to make the camps desirable places for people to stay. I also strongly support only resettling people from camps - but I honestly don't know how we would balance that with the belief that ISIS will be overcome, and the possibility that the fantastic diversity of the Middle East will be lost forever. Of course, lives are worth more than culture - so I think we need also to improve conditions in the camps enormously, and create more opportunities etc there The issue, though, is money - and though every year UNHCR has had pledges from states, only approximately half of that money ever materialises.
