If you need to pump regularly and want to hire a pump a highly recommend the medela symphony. The only problem with this one is that it isn't portable. I'm pretty much an exclusive expresser and use the medela symphony at home but also need to have one for when I'm out and about so I use the medela swing for occasional expressing when I'm away from the pump at home. It can be battery operated and I find the suction to be really adequate. The downside is that it is a single pump, but that's okay for me for the occasional pump away from home.

I hope you can get BF established! It took me a little while to work out how to occupy and feed one baby whilst on the breast pump. It's very possible but definitely not as easy as if we could BF but I guess it's the next best thing.

Wishing you the best of luck!!!
