Breastfeeding. If you think about it, nursing is something we really only focus on for a very short period in our lives. I nursed my kids collectively for about 2.5 years. (Of course, if you do the twin math it is more like 3.66. You get to double everything with twins, right? 😉 ) That’s a long time, but in terms of a lifetime, well, it isn’t that long. I mean, I was in college longer than that. Yet when you are in that time period it is everything. You spend hours of time nursing, not to mention the hours of time spent thinking about it and worrying about it.
