Ever since Child's Play, I know very well that one fine day dolls will really f*ck your life up. And Annabelle represent this very well.
Annabelle was before The Conjuring and it tells the tale of the doll that was given from a husband, John Gordon (Ward Horton) to his wife Mia Gordon (Annabelle Wallis) as an upcoming gift for their soon-to-born child. Everything went wrong when the doll was curse one fine day by a dying cult member, Annabelle Higgins who committed suicide after her partner was shot by the cop shortly after she murdered her own family and invaaded the home where John and Mia Gordon lives in.
TL;DR: Throw all your fooking dolls. That is the end of the problem even a priest can't help you.
