currently we are using the MASAFI water , which is filtered in UAE , and its ok with our 4 months old baby ... but remember that the baby does not drink water !! this water is to mix with the powder milk only .. also we used to use pre-mixed milk Similak brought from the states but its not available here in Doha and then we tried the powder similak , but it didnt work and now we are using Nan #1 milk and its ok
