Good quality baby car seats can be found here but they are very expensive - same for strollers. I would suggest you buy them and bring them with you as the selection is limited as well (mostly British/European brands that meet Western safety standards). Baby gates can be tough to find as well.

You can buy these things online and have them delivered via an Aramex account (some companies will not ship outside the US - Aramex gives you a US address for delivery, then couriers the stuff here for you)

For more recommendations from expat mothers I would suggest you visit www.expatwoman.com - they have country specific and regional forums for this region where you can get info from other mums.
