My son pays £400 a month for his two, when he was training in the job he's doing and his salary dropped back during that period we topped that maintenance up to the full amount. I buy them school shoes and other miscellaneous items when he brings them to stay with us every other weekend. I try to maintain a good relationship with their mother, even though their split was down to her having an affair, conducted whilst he was at work. However, we have to move on for the sake of the children and we remain on talking terms, I resist getting into text wars with her and try and keep our relationship cordial, I will always invite her in if she drops them round. He's moved on to subsequent partner. Fathers that split from the mother still need to make those children their priority in contributing to their upbringing.
