Preparing your baby's feed: Using a clean bowl and feeding spoon... Mix 1 spoonful of cereal with... 2 spoonfuls of warm, previously boiled water and stir. If serving warm, check temperature before feeding. As your baby's appetite grows, use a larger spoon to make a bigger serving. This is only a guide, if you want to alter the consistency, add more or less water as required. Let your little one's appetite lead the way.
