Child Support

First off, I'm one of those who truly believe that child support shouldn't have anything to do with visitation. With that being said, my sons father is GREAT. He's a great dad. Loves his son, spends time with him often, etc. BUT he will not help me financially with daycare or anything else. Daycare is $700/month. We are not on any type of papers for visitation or child support, but I'm thinking maybe it's that time? We've been split for 3 months now and he hasn't helped with anything financially.  I tried to talk to him about it and ask for help but he won't communicate with me about money at all. 
Should I just go ahead and file for papers because of his lack of communication?
