Pierrette has told her parents, and we've told my mother and sister. My father is next; we're seeing him this weekend, so we can spring the news on him then. Pierrette's also told Lisa, I think she was the first to hear.
We'll have to tell the rest of our friends soon enough, but I'm not in any rush.
The baby is now seven weeks in; his or her heartbeat would be detectable on ultrasound, I'm told.
It still feels a long way away, but it's exciting.
