S.B.
I can relate to how you feel and it's ok to have mixed emotions. I have three children now, 9,7, and 1 1/2. My last 2 were "surprises" with the 3rd leaving me devastated when I found out I was pregnant. I was not ready (when are we are we ever) and had too much happening at that time and alot of stress, and was pregnant after 6 years, right when my kids were getting more self sufficient. I felt very very guilty later for feeling this way, but fell in love with him (of course) and now could never dream of living my life with out my baby. I call him "my favorite"! I feel spread very thin as well because I work full time, and my husband works nights, but my kids love to play with their baby brother. Having the support and love from your parents and siblings is priceless and will only become more valuable as life goes on. I say, if you and your husband are not 110% sure you are done having children, then don't go through the sterilization process. You may regret it later if you start to have a change of mind, and may even become resentful of the other if you at all felt pressured into the decision. Bottom line, no matter what, if you some how had a third child, you will love them just as much as your others and cannot imagine your family or life complete without them.
