the baby is in Heaven and she is in hell
In this case, I believe she is forgiven.
Romans6-13
6 But the righteousness based on faith says, Do not say in your heart, Who will ascend into heaven? (that is, to bring Christ down) 7 or Who will descend into the abyss? (that is, to bring Christ up from the dead). 8 But what does it say? The word is near you, in your mouth and in your heart (that is, the word of faith that we proclaim); 9 because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. 10 For with the heart one believes and is justified, and with the mouth one confesses and is saved. 11 For the Scripture says, Everyone who believes in him will not be put to shame. 12 For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him. 13 For everyone who calls on the name of the Lord will be saved.
Oh, did you get a personal call from God to let you know this woman's whereabouts? Sorry, a bit, for the sarcasm, but I don't think so. Please don't assume that God doesn't understand mental anguish, and that we all sin in many degrees.
Leave that decision to God---it is His, not ours.
