Hello All I have been working on several projects where we are looking at postal surveying the duration of exclusive breastfeeding of babies. It seems a rather difficult question to structure so that mothers will give the response we require e.g. if you ask a mother how long she breastfed for, she will give the total duration. If you ask her when other fluids were introduced, you need to be rather more specific i.e. how much other fluid constitutes the end of exclusive breastfeeding? What about the pre-term baby who was given some formula initially but is now fully breastfeeding? What do you class the preterm baby who received fortified breastmilk? Help!
