Lost my 6 week old son

My name is Danielle, I'm married and work as a PreK teacher.  My husband and I have a 9 year old daughter and on February 20,2014 had a beautiful son named Matthew after trying to concieve for 2 years and taking 3 rounds of Clomid. We were thrilled. Our son was a fussy baby from start but never did we anticipate him passing away on April 7,2014 from SIDS.  My world is hell, I found him lying face down, I performed CPR I called 911, I had to call my husband and I had to tell our daughter.  We are trying again, our daughter is on board with the plan as well. Think I just wanted to tell someone my story.
