Little one is 3 weeks old tomorrow. Managed to breast feed and top up with ready mixed formula but breast feeding is no longer working for us. Switched to full formula 2 days ago, have perfect prep machine for home which is amazing no issues there. What do I do when we go out? Take sterile bottles.. buy those powder storage pots with correct amount in.. take a bottle of cooled sterile water (how is best to store this? In a normal bottle or is there a proper bottle to do this?) and then a flask of boiling water?.. then add powder, boiling water first and then cool sterile water appropriately to mimic perfect prep machine? Is that right and safe? Thanks in advance x
