The middle east is child friendly? Erm what? Since when?
Egypt is a shit hole for kids! Everything's dangerous, rusty, i'll maintained, no pavements, driving is so inept as to be a complete joke, and kids are mainly dragged around all night because the parents are out, and only when they're big enough to run errands for their parents are they of any use.
Maybe other countries are different, but morocco's the same.
The only people these places are 'good' for is men with a bit of money and a blue tablet.
Pathetic doesn't begin to cover it.
But then again I wasn't in an expat compound, behind walls with armed guards perhaps it's a different story.
OP, before you even consider this, see what the support is like for thé trailing spouse. Are there welcome meetings, are there functions that include families, are there opportunities for you to have a good amount of family time.
If you're unlucky like MANY who do go out there, you could end up in the loneliest place on earth with a H that's flogging his guts out all hours and partying after work too.
If it works well, it could be the making of your family, if not, it could sink your marriage.
Be very aware of the stakes here. Look at your career prospects too longterm.
