Hi Jayne, No Problem. I am sure your children will fit, that won't be a problem, they will make many friends. When you view the schools, go during school time, so you can see how it feels. You never know, you may be offered a job there yourself, teaching assistant or something. Sometimes these positions come up and this may mean your children go for a discounted fee(or none at all) as your working there. My personal findings (and this was just me, not speaking for millions) was that I found that my children had already covered or learnt the ciriculam some schools were studying presently and there reading and writing was maybe a year or two advanced. (if that makes sense) to what some classes were learning. So my kids looked brilliant, high acheivers etc... but I felt it could set them back. Just my opnion.
Life style will be great, but the day to day activity of shopping, driving, negotiating can be a pain.... but then again, all countries have there dislikes. I wish you great success....
