On the basis he says he does 104-155 nights of childcare a year when he doesn't?
It's more like 80 nights most years and will possibly be almost 100 by the end of this year due to dp and I having a 2 week holiday for the first time in 3 years.
This month he's having them only 3 nights as he works abroad a lot.
Will the csa listen if I can prove he doesn't do as much as he claims?
At the moment he's saying he'll cut the debit by next month. 
bit stressed out as it makes a big difference to us.
