Children and NDEs

I can’t shake a news story I heard the other day. A 16 month old, by the name of Jailyn Candelario, was put in a pack n’ play and left to die by her mother. Her mother, Kristal Candelario, went to Puerto Rico to party for 11 days with her boyfriend. When she arrived home, Jailyn was deceased and extremely emaciated. I think about her so much. She was left alone to die. My question is… do the soul’s of children forget about their traumatic experiences here on earth once they cross over? Since they are so young, do they continue to mature until a certain age? There’s certain evil on this earth I just can’t wrap my head around when it comes to children. Thank you
