Our arrangement happened in mediation, it’s not court ordered. He’s not doing his half. I am OK with the idea of doing more but would like whatever I am doing to be formalised rather than feeling I am constantly on call for when he can’t / won’t parent. Does anyone have any experience of changing the arrangement? How did it happen? And what do I do in the meantime? I am picking up the slack & keeping a record but is there anything else I should be doing?
