Joint account - best way to split?

[fandangofandango]

Hello!

What's the fairest way to contribute to the joint account in this scenario - pre-DC each of us put same amount into the joint account - all fine.

Post- DC, more like 70% DH 30% me - I took redundancy in pregnancy with the view to working for myself so tried to contribute as much as I could from freelance work while looking after DC (DC only in nursery from age 2, and only 15hrs - and of course Covid impacted that too...)

Now DC will be starting school and I can start up my working life again but as my earnings will fluctuate, what's the best to split the joint account - 60/40? I will only be working until 3pm and then in school holidays that would be impacted so unsure on best way to do it . Wondered if anyone else had been in this situation.

Thanks @HarvestFly - I definitely put as much as possible through the joint but I hadn't considered something like my mobile. Will be interesting for me to sit down and work out what it could look like if we did go with that method.
