Hi, I strongly recommend Evian. It's a bit more expensive than other water but it's worth it and you find it in all Carrefours. You can never be sure about other producers here unfortunately...if you decide to go for another brand, make sure Sodium content is less than 20. We just arrived here a month ago from the UK too and my 6 months old is on Evian. My 5 year old was also on it when she was little. Also, what formula are you using? they are not always identical to UK ones. I tried Nestle's NAN but it gave her green poo so we switched to Aptamil and she seems to be fine now. I don't know if it's your first baby but in case it is - don't worry to much about what is so called "recommended milk intake is" - both my daughters always took at least 30% less than was recommended for their age and their weight has still been absolutely normal. Feel free to send me a personal message if you need more advice.
