I.P.
First of all how old is your daughter? Breaking tragic news is never easy to do at any age. Sit her down, and get her comfortable to prepare her for the news. Depending on your religious views, I found in my life the easiest way to tell a child something like this is to use god to announce it to them. When my first son passed away I had to break it to my sister who was only 4 years old at the time. I told her that God came and took her nephew cause he needed more angels to watch over loved ones and make sure we were safe, and that god was going to take really good care of him and keep him happy and safe up in heaven. When she started to cry I gave her loving arms to hold her and told her that it was okay to cry and miss him, and then sat and made a memory photo album that was all hers for her to see him all the time, she is 18 years old now and still carried that album with her everwhere. I hope this helps some, I am so sorry to hear about your loss, and I hope that you find the right way to tell your precious little girl what happened. With deepest respect and appreciation, from our family to yours you are in our thoughts during this tragic time in life.
