If you're son is small, I'd assure you that its preferable to have someone who is already a mother look after him! ... as there are some basic instinctive items on the agenda that will not be appreciated by someone who hasn't done the 'birth-thing' yet !! Go for a mum, whether she is an indian/philipina or other asian background. On the other hand, you might get lucky and get a part-time sitter from among some of the bored (not boring!) women on expatwoman.com (Doha does have its boring moments). They might be happy to babysit, providing the perks are good enough. There was a thread long time back, about sharing babysitting among families.

European nannies don't exist per se here... and if you want to bring one in, you'll have to make sure they are over the required age minimum (around 35). Salary will relate to their country of hiring too, which will no doubt be far more money than 'normal' rates over here.
