I would actually replace the picture that's just of your son. The picture of the 2 of them is adorable but the one of just him is a little weird since it's her birth announcement.
This is exactly what I was going to say. I think it's weird to have just a picture of him since it's her birth announcement. Even if you skipped Christmas cards this year, I still find it weird. There is already a picture of him with his new sister so out of town family and friends can see him there. If it were me I would replace that picture of him alone with another picture of her, since that's what you are announcing.
Or you could add another picture of them together.

Yeah that's another great option. Do you have anymore of the two of them together?
