I've been window shopping in the baby porridge aisle as dc3 is 23w and I'm looking forward to trying solids with her. Now the instructions on all the baby porridges say use warm previously boiled water. But they contain follow on milk, so would I have to faff about with letting kettles cool for half an hour to make these safe, or is it different after 6m ? I know I can use 'normal' milk but the baby porridge all has milk in already and is easier to make than ready brek.
