Hi girls. I would say DEFINITELY buy a pump BEFORE that babies come, that way you are more organised and can sort out how to use it etc. I bought the m....a instyle advanced which has double pumping (or single) and its fantastic. I still use it 2-3 times a day, but more so in the early days especially- to build up my supply and also because Addie and Will were in special care for a couple weeks. Even if they hadnt been early, i still would have been pumping to keep my supply up, and also to have that bit extra in fridge/freezer for emergencies.
This pump was recomm by a friend who is a counsellor with the ABA, and i couldnt have had any better advice! It is designed for more frequent use than some others, but is quite expensive. I bought mine from toys r us when it was onsale. If you look at it though, the cost of hiring a double pump adds up and it sort of cancels itself out in the end, and if you are determined to BF, then it is a really good investment.
Any other questions, feel free to ask.
Good luck girls, busy days ahead!!!
