Hey Christina, you found the right place if you want to connect with openly compassionate people that won't try and comfort you with fairy tales. I am so sorry for your loss. It is a tragedy to lose someone you love, especially a child. I could not imagine what you feel, but I can offer some words of relief.....my way.
I am not into reincarnation or anything, but I believe that the things we are as humans, the simple elements of the universe, return to the universe and the energy we are as living beings becomes a part of the cosmic harmony. I'm not going to tell you any god stories or tell you it is the "will of god", etc...etc... or any other nonsense. All I know is that when we pass, we in some way join the else and become one with the magnificent infinity.
We have no control over the death of others, but we can take in the joy of knowing that they are at peace, they feel no pain or fear and who they were lives forever etched in time.
My most sincere love and sympathy is extended to you....may peace be with you.
