Hello. I have a question. I have a 9 day old baby I have been breastfeeding. I have to go back to work after 6 weeks. I have read some forums that say it is not good to feed and pump. As of now, my daughter only feeds on one boob per feeding. She eats about every 1.5 to 2 hours during the day. When should I start pumping so that there will be supply when I go back to work?
