DS (17 days old) is currently EBF, and will be going to nursery 3 days a week in January when I go back to work. I'm hoping to build a stockpile of frozen breast milk so that he can continue with breast milk from a bottle while he's at nursery during the day, I can express at work during the day and I can still breast feed in the evenings and at night. At the moment I'm expressing roughly 100ml twice a day using a Tommee Tippee manual pump, but obviously will need a pump that will express a greater quantity, more quickly (and preferably hands-free) to use at work. I've been looking at second-hand electric double pumps, the Lansinoh Affinity and the Ameda Lactaline are the two that seem most available second-hand and are roughly the same price. Which (if either) would you recommend, or would you suggest slashing out extra for a brand new one - if so, are either of these two any good? Thanks in advance!
