9/10 times the kids, particularly the boys get worse. They pick up on even worse habits like khat and extreme laziness. Due to the war, there are serious social issues and undiagnosed mental health issues back home that is brushed under the carpet.
I think taking your kids back home is great, providing that you actually go with them and keep an eye out on them. No one will look after your kids the way you would. Also, recently I've been hearing many cases of kids getting abused when they are left there. It really shouldn't be a suprise though.
