Sandy, Is this mom going to be doing her mission work with friends that she is very comfortable with? If someone is willing to take the place of the electric pump, there is a way to do it. I have access to L--t--a pumps that are owned by the district WIC program, but don't always have one immediately available. Since this pump is a mechanism that pulls on a hand pump connected to tubing, it works if someone operates the hand pump. It allows double pumping. I have had some parents use this method when traveling. It can be tiring for the person operating the pump, but it works OK if the woman doesn't mind having another person around while pumping. If the mom can learn to hand express, that is another possibility. My daughter is almost 16 years old. At that time, pump selection was quite limited. I was able to collect milk pretty efficiently when I went back to my job. Several other women I know also went back to a job outside the home and expressed the milk directly into the bottle. (The skill of hand expression comes in handy when moms fear that they do not have any milk or the baby needs a taste of milk to help him latch on. After asking permission, of course, I express a few drops of the mom's colostrum.) Since she is going to be away from her baby for a week, storing milk doesn't appear practical, so pump and dump sounds like what she'll be doing, unless there is some other use for her milk. As far as storage of pumped milk, there has been some research done on the microbial count of milk stored at room temperature. I remember hearing that the bacterial count decreases after 30 minutes, but don't remember when it begins to rise. There are also the questions of What is room temperature in Haiti? and What facilities are available for cleansing hands and storage containers? So much for my .02 Becky
