Parents! What do I need to bring/ not bring for the kids?

Bring a year worth of clothing, toys, even their oncoming b-day presents, we bring presents for future birthday parties that our children might be invited.
I don't know prices in the UK but we buy from North America and prices here are so much higher, besides, not all the brands we like we can find.

Bedding is always good, tanning lotion, personal care brands that you like.

In any case, after you live here, you will see what you should bring after your first re-pat.

Good luck

My view isn't as dire - we didn't need to bring a year's worth of clothing. We wouldn't have even been able to - the shops were stocking winter items when we moved! There is a host of familiar shops that stock children's apparel here: H&M, Mothercare (for wee ones), Gap, Gymboree, Pumpkin Patch, Monsoon, and there's a few more that I haven't checked out yet. Apparently, Old Navy is opening in the Mall of Dhahran. It's easy to find clothes for my younger kids, but my teenager is a little trickier (haven't decided if there are fewer options or if he's just picky). Yeah, things cost more, but they aren't a larger proportion of our income, so it's not worth panicking over, really.

I'm not sure if there is a wide assortment of bicycles for children here; the reports I've heard suggest that the selection isn't as broad as in my home country. We bought our kids new bikes before we moved so as to include them in our sea shipment.

We packed too many craft supplies. I needn't have stocked up; there's a good selection of craft supplies between Jarir's and Zamil's.

Most of my children's favourite brands of toiletries and sunscreen aren't available here, so bringing in some extra never hurts.

Toy-wise, there's Toys R Us, ELC, and Hamley's, but their selection isn't always what my kids are looking for compared to the shops back in Canada, so some items get put on their birthday wish-lists and such. I'd suggest bringing educational board games with you (I'll pass along the advice I received to leave the dice at home); the selection here is smaller and not as high-quality for sure.
