I had a hand pump too, but found it really hard work. I was really lucky and found that I managed to express enough for two babies quite a lot. I've had a few friends who have really struggled with expressing, and couldn't get much at all. I certainly wouldn't want to exclusively express again, it was exhausting, and I think it would probably be even more difficult with a toddler to look after as well.
I think I need to start getting organised pretty soon - I need to dig out DS's clothes, car seat, snuzpod etc, as well as painting the babies room and getting the carpet cleaned and buying new nursery furniture. It's felt like I have ages to get things ready, but a friend has her baby 5 weeks early recently, and that's made me think I need to get a move on! Though I need to get Wednesday's exam out of the way first!
