How to move to Finland with a baby

I wondered if anyone can help.
I currently live in the uk with my son.
His father is Finnish and lives in Finland.
I would like to move to Finland to be closer to my sons father.
I wouldn't be able to work at the start as my son is only 16 months.
Can I move?
If so how do I go about this?

Annabell, how can we answer your questions when you don't tell us anything about yourself? Are an EU citizen? Are you married to your son's father? Does he want you here?
