hi swoon, i certainly wouldnt change destinations! Buy the bottled water with the baby danone symobol, its a babes head with stars, or the bottle nipple. Water with either of these symbols inidicate the mineral content is fine for infants. To bring readymade is very very heavy. Boild the bottled water if you want, but no need. Two tins of powder formula, with a few readymde cartons is plenty for a fornight hols. Spain is a loveley place to bring a baby, have done it several times myself. Just a tip, check before you go that a kettle is provede in your accomadation, not all of them have one. Youcan request it, or just bring one with you. Our fist year with an infant we had to buy one. No major hassle, but try finding one on your first night when everyone is knackered!! This is hwen the readymade comes in very hand. And keep a few cartons for the trip home. You never know when you could be delayed in the airport. HTH
