No. That is the short answer... If you're used to doing stuff like you would in Europe/UK or the States, then QR 10k is not enough, for you your partner and a young child. Anyone who tells you it is, is not being honest. If however, you don't like eating out at a decent restaurant occasionally, and have no need for personal grooming/hair cuts/ mani/pedi's etc, and no need to join a club/gym/spa/beach resort etc, for recreation (as there is not a lot to do here...) then yes, QR 10k is enough!!
If I were you i'd negotiate upwards. Or don't move here. The cost of living is high in my view...
