We lost our first one at 24 weeks, he had rare genetic condition and couldn’t survive. I remember holding him and giving him a kiss, my wife gave him a little bath and dressed him. We left the hospital a few hours later completely empty, drained and void of emotion, completely numb.
I can’t say it gets easier with time, it hasn’t, some days are ok others a harder. I liken it to carrying a pebble in my pocket, some days I don’t notice it, others I can feel the pressure and some days it digs in.
Try to keep yourself well to look after your wife, try to talk about it, it really does help. Make time for yourself as well.
