I agree with Ecologic that this will be hard for her and she may stay away for awhile. It doesn't mean she is not happy for you, but it is certainly a reminder of her tragic loss. I too would not hide it from her, but be gentle with the news. Try not to discuss it in her presence. Congrats on your pregnancy, and I wish you all the best!
Don't hide it but prepared to have this relationship cool down. Your friend may need some space and time.
Hi. I was that mother who lost her child and don't hide it from her is my advise. I had a situation similar to yours and yes it hurts, but everything hurts at atime like that. My friend gave birth to her beautiful baby boy 6wks after I lost my beautiful baby boy, he was the only baby I could bear to be around because she had struggled with a difficult pregnancy and this boy born with Down's syndrome was a sign of hope to me even at the worse time in my life
PS.... A year later I gave birth to my gorgeous daughter who amazingly also has Down's.. She has healed a lot of my pain, although it's never far away, your friend will always carry that pain, but she will be pleased for you.
I had to do this and know how you feel. What i did was break it to her a little at a time. I first told her i missed my period...but i an waiting to take a test until next week. then a week later i told her i was infact pregnant. We are very close and i am considerate of her struggle to get pregnant so i don't always talk about the pregnancy.....that's just what i did.
