Sharing our news

Jackie
Ok ladies I need some advice. We are planning on sharing our news on Christmas. My brother and sister in law will be there too and we are super close with them. I'm nervous about sharing the news with them though. They have been trying for about 2 years now with no luck. They've even started seeing doctors to try to figure out what's going on. They don't talk about it much so i don't know much but I'm worrying about upsetting them with our news. My husband and I only started trying a couple months ago  and I need some advice on how best to handle this. Thanks in advance!!
