I am so sorry for your loss. It is a horrible thing to bury a baby. I can definitely sympathize with you. I lost my precious baby boy to SIDS 4 years ago. I miss him so much. I still cry almost every day. I can't say it really gets easier with time but you do learn to cope with it. I think talking about your loss and remembering the happy times with your nephew will help. I got stuck just focusing on the death and that's not healthy. Cry when you need to. Don't hold it in. Check in on your brother frequently if you can and just let him vent to you. My thoughts are with you and your family. Feel free to message me any time if you'd like.
