Whatever you feel comfortable with...........

With pregnancy # 1, we were cautious and waited till I heard a heartbeat at 12 weeks, then sadly I had an mc at 13 weeks. So I wished I hadn't told anyone at all.

With pregnancy # 2 (Olivia) we waited until we had heard & seen the heartbeat and had a lot of reassurance from my OB before we told anyone at about 15 weeks.

With this pregnancy we had a scan and saw the heartbeat at 8 weeks and that was just before Christmas, and we were seeing my IL's interstate at Christmas (and were staying with them) so we told them as they would have guessed from my lack of wine swilling!!
