There are definitely some medicines that are not available here. I don't remember what they are offhand (sorry), but you'll want to stock up a bit and carry them in your luggage so they don't heat up too much.

There are plenty of expats here with young children. . .and plenty having babies here as well. I think things can be a bit more difficult to find, so it's worth shopping ahead if you can. The toys here can be a bit junky, I've been told, so bring some toys for your kids to grow into. If they have something unique about them physically -- say, extra wide feet or a big belly-- buy ahead to get the stuff that you know will work. Driving is a pain in the butt here and you don't want to be hauling two kids all over town looking for something.

Take a look through your kitchen as well to see what you can't live without (e.g. real vanilla extract) and bring it with you. I brought Meringue Powder in large tins, vanilla, maple syrup, double-acting baking powder and all sorts of other things.

Unscented laundry detergent, if you use it, is something worth stocking up on. I have found it once and the box had already been opened; I purchased it nonetheless.

Anyway, I got away from your question but it still might be useful info for you.
