Do I need a breast pump?

Bex

I'm not working at the moment, although I am looking for a job and I dont know if I will have one at all before or after the baby comes.

I plan to exclusively breastfeed for 6 months.

So do I need a breast pump at all?

If I do will a cheap brand do, since I wouldn't be using it often?

Manual or electric?

Best brands?

Worst experience?
