With DS, I worked less than a mile from home and XH dropped me off at work, so not only was I able to nurse DS during lunch and immediately before/after work, he could bring him to me to nurse if necessary. This time, I work half an hour from home, I work retail so I don't have a set schedule, and I take the only car, so DH can't bring me DD if he runs out of milk. Plus I'm often scheduled for 4-hour shifts, so I don't get a break and can't pump. I end up pumping on one side while nursing DD on the other when I get home to try and get milk for the next time I work. I don't get a lot from the pump, so it often takes two pumping sessions to get enough for one bottle.
I never felt the need to have any "just in case" formula in the house with DS. I've ordered a few samples to have handy for DD. With me working so far away, I worry about there being an accident or getting a flat tire or getting stuck in the snow. I don't have any other nursing moms handy to get extra milk from.
Did you have any formula around for your exclusively breastfed baby? Did you ever end up needing it?
