Hi! I'm 9 weeks pregnant and have a 3 year old (he just turned three). We told him as soon as we found out, around 5 weeks ago. He's taken it well-- excited and all, although he wants a little sister and, well, there's nothing I can do about that. We talk about it with him, not too much, but as it comes up naturally. Don't worry, just tell him what's happening, what will happen and be prepared for the questions! (Where is it? How will it get out?) Good luck!
