In Alabama, if there is no contact in a 6 month period....the CP can take further action.
In my personal divorce (WV), since it was long distance, my parenting time before I retired included 6 month stretches of not having time with my son.
Even in my first divorce, Dad received Summers and alternating Christmas'. It was a fairly old divorce -- before the ones of "this newer generatation" like 1989....(Thanksgiving and Easter were not included back then and it was long distance)
See if you can find something in your state's code that talks about abandonment and time periods associated with that.
