Nervous to announce

My husband and I just found out we’re pregnant with our second baby (due in late January), and our first is only 7 months old. Our first baby will be 14 months when our second is born. It was definitely a surprise as we tried for over 2 years before getting pregnant with our first but we are obviously very excited. I’m nervous to tell anyone, which I know we will have to do eventually. Does anyone have any suggestions on how to announce this in a way that won’t spark up the “oh wow, already?🙄” comments?
