@Ikeptgoing I'm sure I won't convince you and I've attempted to be as clear as possible without publishing my the entire schedule and finances for each family.
Currently the children are with me 5 days a fortnight during term time or 2.5 days a week. It is entirely "accurate and mathematical" to say that that's 1 day a week less than 50%. Yes mum now does 2 days a week more than me but one of those would be her responsibility anyway if we were 50-50, so I only "owe her" for one extra night a week in term time.
In any case my initial and much slated breakfast post was questioning how reasonable the Child Maintenence rules are for a proposed change where the children would be with me for 5 overnight stays and 2 evenings per fortnight.
Currently the children are with me alternate weekends Friday school to Monday school (I'm already going to the school every day for DS2). They are also with me one night a week - school to school.
The proposal is that I pick them up from school on an additional night - flexibly around her shift patterns, give them dinner and then drop them back in the evening, so they see mum then or at least in the morning.
This additional evening cuts down the current the week long break from Thursday morning to Wednesday evening where they don't see me, their little brother or stepmum.
We'd be 50-50 care in all ways apart from me dropping them back after dinner one night a week in term time.
I'd continue to be the NRP and according to the rules she could still demand I pay >£500 per month.
To me that seems unreasonable especially when it then impacts what I can afford to do with the children. Yes that ~£550 per month is not just paying for 40 breakfasts a year - it would also be 40 packed or school lunches a year, and it would be showers and laundry. It's also true that because I'm currently forced to pay maintenance I don't currently pay my half of their £250 a term music fees, and mum's bought the last few sets of school shoes, and pays for a hair cut per term. However even if I also stopped paying for any school trips and demanded she bought all the uniform it still wouldn't add up.
Aside from the money which is a tangible factual thing, as soon as someone is branded the NRP, they are immediately treated as a second class parent. People, assume NRPs don't pull their weight, know nothing about the costs and stress of childcare. NRPs are either not contacted or contacted last about anything regarding the children.
Re, holidays, bank holidays, inset days and sick days. Yes we now officially split holidays 50-50 - that was how it had normally worked out but she was giving me more time with the kids as a favour to me to take it up to 50-50, it's now agreed that we will split 50-50. Bank holidays / inset days they stay with the parent they were with that weekend. I don't work bank holidays and have to look after DS2 on inset days anyway so I've been a bit gutted when it's not been my weekend but also grateful to spend time just enjoying DS2 (even if he'd rather DS1 & DD were about). Sick days are flexible around our work/shifts (I'm fine working from home with a sick kid snuggled on the sofa, but if mum's not working and the kids are already with her).
