I too can sympathise. I had brought things for both of my angels, which I did end up giving to my SIL (after both of my losses she got pg) so it was easier to give things away. I got the joy of knowing and seeing another baby who was precious to me get to use these things. I have also recieved some of them back for my baby I am pg with now and it is nice to have a bit of history to them. Though they were not as big a a bassinet- only things like blankets and clothes. Although from both pg, I kept one thing that was especially precious- a lovely blanket from my first angel and an outfit from my second. I put them away where I did not see them, only when I wanted to and was mentally and emotionally prepared for it. Now I have added them to my stash of things for this bubba and I am at peace with the knowledge that my angels will have some part (albeit small) in their brothers/sisters life. I think you should hang onto the bassinet. Although it may have painful memories now, one day you will be able to look at it and remember the joy and hope you had when you first got it. And then you can put your angels' brother or sister into it and smile. Maybe put it away from sight though, so you are not too upset by it at the moment, IYKWIM. When you are ready to do something with it you will. know.
