Thanks for your patience.
You are going to have to try formal channels to put in place something that is going to be regular and reliable - for both you and your child.
Mediation has to be the first point of call as it is a legal requirement prior to issuing an application in the family court.
You start this process by attending family mediation - see here for a link to find your local mediator:
Assessments are usually around £30-£40, and the mediator will advise as to how many sessions might be required. Mediation is a collaborative approach and allows you to talk through issues and concerns in a safe and protective environment.
Following that, if the mediation does not succeed in a successful agreement, you can apply to the family court for a child arrangements order (see below description), setting out the living arrangements and contact arrangements that you would like to see.
You would apply on a c100 form, here:
You send 3 copies of this form to the local family court centre.
Alternatively, you can apply online:
There will be a court hearing after you apply and a family court adviser will be there in attendance too (from CAFCASS).
The application costs £215.00, and you can represent yourself so you don't need to engage a lawyer. You can also possibly get a fee exemption if you are on low income/have low savings.
For this you would need to fill out a fee exemption form: http://www.gov.uk/get-help-with-court-fees
