Alex, i dont think your ex will agree to a contact order, thats why you will have to take it to court - sadly.
From experience, if you love your child and can offer valuable experiences and most importantly LOVE, then going to court will be cool. It proves to your ex that your serious about seeing your baby.
Can i also add that you can instruct the CSA to pay a nominal amount from any benefit that you receive = �5.00 per fortnight. That also goes in your favour as any Judge can see that even though your not working, your still comitted to paying towards your baby's upkeep.
Good Luck and best wishes
