Hi Ladies, i need some advice on expressing milk. my midwife advised me not to express until the twins were 3weeks old, that way my milk supply should be well established. So i started expressing this week, but im not sure how often i should do it, i am looking to express to have a back-up when needed so i am still breastfeeding at every feed. can i express between feeds or will this decrease the milk available for the twins at the next feed? they usually feed every 3 hours. i read that breaSts produce on the demand of the babys but if im expressng in between is this helping produce more milk or using up the milk for the next feed? how often can i express a day? any advice would be great.
