I want to start pumping so when my son is crying and wants to eat on demand like he does my mom can atleast take him so I can get some sleep! Idk what kind of pump my insurance offers( I have fidelis/Medicaid) but I do have a manual pump the hospital gave me... What do you ladies think is better manual is electronic ? And also bottles? I got a a few avent bottles. But I also have 1 man bottle, a latch bottle and something else. What have you ladies all found to be a good bottle? I'm hoping my baby will take to the ones I have.
