I'm wrestling with what is fair in this situation and could do with some suggestions.
DP and I both work and we have a DS aged 18 months. DP works 5 days a week and I work 4. DS goes to nursery the 4 days I am at work and is with me on the 5th day. Having DS one day a week is completely my choice and I love spending the day with him. I could go full time if I wanted but I don't want to.
We have always had a joint account out of which we pay all household expenses including DS's nursery fees. DP and I have historically always paid the same amount in each month to the joint account except when I was on maternity leave. Our full time earnings are broadly the same as one another. Whatever is left over after we have paid into the joint account is ours to spend individually as we wish.
Now that I am working only 4 days compared to DP's 5 I am earning less. I am also obviously saving us as a family the cost of a 5th day of childcare.
Should I therefore be paying less than him each month into the joint account. Should I be paying 4/5ths of the amount he pays?
I am obviously also losing out in terms of my disposable income as I have less left over to spend on myself than he does. Is there a solution to this or should I just suck it up as it's my choice to have DS for that 5th day?
It wouldn't work for us to pool all of our earnings and then take out equal amounts to spend on ourselves so what is the best/fairest solution you can come up with?
