My mother has been helping and factoring in childcare would be part of the affidavit but my point has always been that I’m willing to shoulder some of these costs by means of having the children more often. In my view this would be a two fold benefit whilst reducing costs and keeping some normality for the children for all concerned. I am lucky that I can change my working hours to enable greater flexibility.
I see what you mean regarding “splitting of extra expenses” and yes I have already started a spreadsheet outlining all my projected expenses once I move out.
