I recently got a sample of the HIPP organic mineral water with fruit extract drinks which they say are ok for babies from 4 mths. I gave a bit to baby Jacob today and he loved it. Just wondering if its ok to give these kind of drinks everyday at the age of 5 months (say 60-80 ml a day)? Or should he just be having milk? Are there any 'negatives' to these drinks e.g. sugar?
