finding joy

My husband and I just found out we are pregnant with baby #3. We, of course, are so happy. But my sister-in-law just announced a few weeks ago they are pregnant. Which means our babies are basically a month apart. My sister-in-law is super self-centered and makes everything about her. We want to tell our families sooner then later because I’ll need help with our boys for doctors appointments. But I’m so worried that no one is going to be excited. It has put me in a funk all day. I know it doesn’t matter what other people say or think but we want this baby to be celebrated too. Does anyone else deal with this?
