New mothers always want to know what pump they should use. It's a tough question to answer because there's no one pump for all mothers. I would suggest that moms do some research on their own and go online and see what pumps are getting good reviews. The two companies that I have the most experience with and I can recommend because I know they're good companies that stand behind their product and I've been using them for about 30 years. One of them is called Medela and the other one is Ameda, and they both make a number of different pumps; I think they're quite good and reliable. As far as when to pump and how often to pump, that really depends on what the mother's needs are. A mother who's going back to the workplace full-time is certainly going to do a lot more pumping than a mom who's staying at home and offers the baby an occasional bottle. For example, if you have a stay-at-home mom, she may pump once a week because that's how often she offers her baby a bottle. If you have a mom who's in the workplace, she's pumping three or four times a day to make enough milk for her baby in daycare. So it really depends on what her needs are.
