Limbo or Heaven: Where do the souls of unborn infants go?

I have never believed that unbaptized infants who are not guilty of any personal/actual sins will be refused admittance to heaven. I believe that Jesus, who loves kids so much, would make way for them to be cleansed of all original sin and be admitted to paradise. Christ has completed the objective salvation of all the world so that everyone can be saved. If we believe that adults who died before Christ and obviously were not baptized in his name could be saved, how much more these innocents without any personal faults?
