On the mormonism channel it was brought up lately that Calvinist believe that unbaptized babies that die go directly to hell.. I have read the five points of Calvinism I don't see such a doctrine of condemnation of infants.. Here are those five points, can anyone show me where such a terrible doctrine that condemns children is included in them?

Total depravity (Original Sin)
Unconditional election (God's Election)
Limited atonement (Particular Redemption)
Irresistible grace (Effectual Calling)
Perseverance of the Saints

Thanks for the help IHS jim
