I didn't even think of that! We're staying with MIL but just looked online without mentioning babies and the water isnt drinkable in Majorca because of high sodium content- so I guess that is out the window (Clematis- I had thought the same as you about boiling). Anyone know which bottled water is low sodium?! Or Spanish for sodium!!! Lily- all those cartons! I'd be worried they would leak in my suitcase!
