Split with ex last year, 2 DC (ds13 and dd11) are fine, current situation is alternate weeks with each parent.
Dd has been delaying going to her dads for a while now, finally admitting that she would like to stop the alternate week arrangement, stay with me full time and "just visit dad sometimes".
I'm happy for her to do this, (ex is ambivalent). although the extra costs will be higher, is it reasonable to expect a maintenance payment from her dad to cover the extra time she is here? Her brother is happy to continue with the current routine. In effect I'll have one dc 100% of the time and one 50/50, has anyone been in this situation? how did it work out?
