Don't let any minors dictate anything. It's not their choice, I'm afraid.
We moved 16 months ago with 3 kids (8, 6 5) and we're all loving it.
Their happiness will actually be somewhat linked to how 'involved' you get with their school, their new friends parents, any sporting scenarios that require extra curricular social inputs.
Being brutally honest, if you show any weakness, they will pick that up, and you'll have a problem.
We've had a ball here the last year and a half, everything has worked out and the best is yet to come, our kids have grown immensely at all levels - every morning I thank my lucky stars we made the move.
