We took our son to Turkey twice last year - aged 10 weeks the first time and seven months the second.
My wife was still breastfeeding on the first trip, but we took our own milk powder over for the second trip and made up feeds using boiled bottled water - a bit of a pain as we didn't have self catering facilities. It's generally best if you can keep your baby on whatever feed they are used to.
I agree with the advice about the travel steriliser and sun block.
One thing you need to think seriously about is mossie repelent. You really don't want a badly bitten baby, but adult repelent isn't suitable - again Boots have infant-friendly wipes, and there are a couple of citrus based
products that I can't remember the name of directly - I'll try and find a link.
When you get to your resort ask if anyone can reccomend a good local tailor or dress maker! When we were in Dalyan last year one of the hotel staff took our baby buggy to the local tailor and he made a mosquito net that was really useful when we went for a stroll and a meal in the evenings - it cost a fiver and he ran it up in a couple of hours.
Apart from that the biggest problem you'll have will be local people wandering off with your child. It really happens - they're a lot less paranoid about that kind of thing than we are, and it's a healthy thing imho.
