I LOVED, loved, loved the hands free boustier. It rocked my world! I highly recommend it. I never had any problems with it and I used it multiple times every day for months on end. My breasts were a 40 I, so even with large ones it still works!
Also to increase milk I took fenugreek. There is a prescription that your doctor can give you, I forget what it's called, but don't take that. It made me super crazy and after I stopped taking it I heard other bad stories from it. Fenugreek is an herbal supplement that you can get at any health food store and probably Whole Foods. It will make you smell like maple syrup, which I know sounds super freaky, but it does. Even my husband noticed it, so it wasn't just my imagination!
Also you can drink a beer every night (probably not at work! LOL!) before you pump and it will make a difference. Some people out there will tell you not to even drink one beer, but trust me, it's fine! One beer is not going to make your baby drunk! They will barely get any of the beer and none of the alcohol part. The darker the better worked best for me, but any old beer will do.
