Moroni 8:11

and their little children need no repentance, neither baptism. Behold, baptism is unto repentance to the fulfilling the commandments unto the remission of sins.

Little children don’t need to turn from sins. They don’t need baptism. Baptism is for turning from sins and obeying God’s commands to have sins forgiven.

“Little children don’t need repentance or baptism. Baptism is for people who need to repent, so they can obey God’s commands and have their sins forgiven.”
