ask yourself what is best for your daughter, irrelelvant of the money.
If I stopped conatact linked to child support my son would be asking for a photo to recognise his dad. However my son loves his dad to bits. Contact has been maintained (except a short blip where it was needed to ensure the wellbeing of my child). I wouldnt want to lose that bond for my childs sake. Though it would certainly make my life easier!
