I think that it is totally different for different people. Six months is not very long in the grand scheme of things, although this 6 months has probably feels like much longer to you, I know it did for me. When I had to be around pregnant people/babies, I just kept reminding myself that this baby has nothing to do with me or my lost baby and I do not want my friends/family or anyone else for that matter, to be what I have been through, that helped me get through those moments. It does get easier with time. take care of yourself.
