DS2 is on special formula milk which has to be made with powder, there isn't a pre-made bottle option. I'm wondering if it's even worth going on holiday abroad with the faff of going on the plane and making up feeds while we're there. Has anyone experienced going abroad with a baby on special formula milk? Also - if we have a self-catering apartment, can I just boil the kettle and make a feed like normal? Or is the water not safe? We're thinking of Sicily.
