Hi ladies, this is my 2nd pregnancy im due in 19 days eeek (cant wait for this to be over its been awful this time) with my son who is now 3 I combination feed him from the start breastfeeding for 6 months. At first we used cooled down kettle water then just bottled mineral water when we made his bottle's. I plan to do the combination feeding again but do you think its okay to use bottled water from the start?
