I am going to go against the grain. I think some quite shoddy behaviour is often excused in these situations. I mean no one is going to avoid other people with say, mothers, if theirs has passed away. Because you cant.
I have had 2 miscarriages, 1 ectopic, 2DCs and was treated for depression as a result of the losses. But never did I feel resentful towards friends and family who were pg. I just as sad for me, but made up for them.
I think women who have had losses, should be a bit better at dealing with others pregnancies. It's a fact of life, you can't stay indoors and avoid everyone that ever had a child, it simply isn't possible.
Of course the pg person should be sensitive and considerate, but they should also NOT NOT NOT have to avoid being excited about scans and baby stuff for fear of causing offence-it's a special time.
I am quite angry at my very best friend who cannot face seeing me because I have children. I thought our friendship was more than that. Because if I truly cared about someone, I would want to share in their happiness-not resent it. I think a lot of women no matter how badly they are hurting should not go around being hurtful to other women they are jealous of, because of something that was in no way their friend's fault.
