Breastmilk Production Problem

Kait

My 4 month old is teething and has been on a nursing strike for several weeks now, which has seriously depleted my milk production. We had to switch over to mostly formula. I try to pump 4+ times a day and plan to pump 6 - 8 times now that the craziness of the holidays are over, but I'm only getting a couple of ounces per pump. I'm worried that my supply is drying up....any suggestions or stories from moms out there who were able to get their milk back? I drink about 60oz of water a day...is that not enough?
