Re: How do you tell others when you are expecting again?
We're expecting #5 too.
We were a little nervous telling my husband's parents. They came over the day after we found out. My husband could barely keep a straight face before he blurted out "Well we're going to have a basketball team in January." It only took his Mom a few seconds to figure it out. We are very close to his parents so we weren't nervous to tell them thinking their reaction would be negative, they love being grandparents.
Now I am not excited to tell other people. We already get enough annoying comments from strangers.
You're not nuts and I don't think more children is a bad decision, I love our full and noisy house(most of the time!).
