hi there, i brought my twins to spain when they were 9 months old and all was fine. just make sure you bring the baby milk with you as it can only be bought in a pharmacy mostly.
i brought a tin of baby sma sealed in my hand luggage and then some made up bottles they did not have a prob with this at the airport once i put them into seperate bags when going through so best of luck.
there is a brilliant range of baby jars and food in all the local supermarkets i think we used the hero range and the kids loved the fruit versions.
as a just in case i would bring dozol as it has an anti histismine in it as well as paracetmol as one of our guys seemed to develop a form of hayfever so this worked great. but it also works if they get a bite. you can get microwave sterliser bags in boots which are brillaint and mean you dont have to lug a large one with you.
hope this helps
