I've only read the first and last page of this thread and I dare say that no one who posted here about this topic have really no idea/understanding what Scripture teaches about babies or saved individuals!
Scripture declares:
10) As it is written, There is none righteous, no, not one:
11) There is none that understandeth, there is none that seeketh after God.
12) They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one. Romans 3:10-12
The above Scripture verses is God's assessment of the human race without exception, including babies! Consider Psalms 58:3 also.
On the other hand...
"To be absent from the body is to be present with the Lord." (paraphrased). 2Corinthians 5:8
All individuals who are saved go to be with Christ after death, forevermore.
I hope this helps.
To God Be the Glory
