I am so sorry for your loss. I, too, lost a baby about halfway through the pregnancy. It was a very emotional time, and I still have sad days sometimes - and it has been 4 years. The thing that gets me through now is knowing that God had other plans. I now have a 2 1/2 year old son who was born almost exactly 9 months after our angel would have been born. I know that I would not have had my son if I had that baby. Even though you cannot replace one child with another, I am glad that my son is in my life and I know that I will meet my other baby in heaven.
Maybe God has other plans for you, too.
God bless you!
