Just a rough figure. DD's dad contributed £40 a month for the first two months after we split and since then sweet fuck all. I have absolutely no clue how much a father should be paying for his child and no idea even where to start on getting him to pay.
He is NC with her, however his DM makes a big effort with her. If he's on a similar wage now to what he was at the time I was with him then he will be around the £40k mark.
Side note - I am financially comfortable even without payments from him, WIBU to claim if I don't technically need the money?
