answer:Without a lot of emotion, list those issues and show how they cost you more. For instance, if you have to drive your child to his house, and he has moved beyond a reasonable agreed to distance, then it costs you 55 cents per mile (that’s the IRS mileage rate). If you have him because his father did not take him, you have the extra expense of feeding and caring and entertaining your child when the father should be caring for him. You can list lack of notice of job changes as an obstacle in your finding if support should be increased because of his presumed higher wages. Good luck!
