My husband has the opportunity to move with his job to the US for a period of 3 years and then move back to UK. The company would help in terms of relocation, advice etc (so probably not massive financial risk). We have 4 dc, ds1 8, twins 6 and a 4 yr old. Here we are near to both sets of grandparents so get lots of help, dc very close to them. My eldest struggled at school at first but now has a good circle of friends. It feels like an exciting opportunity, chance to broaden children's horizons, (it would be a good career move) but at the same time I don't know if its fair to take them away from everything they know, family, friends and generally unsettle them. I would also be v isolated with 4 dc while dh at work. I'm looking for general advice, how it's worked out for others? Any advice/experiences greatly received.
