Is it wrong to announce you’re expecting at your daughters 2nd birthday party?

My daughter turns 2 this year about the same time as we would be announcing our 2nd pregnancy. Our family is never all in the same place so we thought it would be cute to announce it there with everyone together. I don’t feel like it’ll take away from her day because she’s 2 and she will be excited about the attention. I’m thinking either to open it as one of her gifts or put on a big sister shirt. If you were guest (family and close friends only) would you think this is weird?
