I have been successfully breastfeeding for 2 months now and am now wondering about pumping. I am not planning on going back to work so I don't need to I guess.but here are my questions Do I need to pump? How much should I pump? Should I rent or buy? If I buy is a manual pump ok? (I am broke) When should I pump? Will it screw with milk production? Do I have to buy bottles and then what kind? Pretty much any info on pumping would be appreciated.
