Unless you're extremely wealthy everyone has to budget, make sacrifices, and make difficult choices about where and how they spend their money.
Hard work and high wages do not necessarily go hand in hand.
My household income is a little over two thirds of yours, but we don't live in London or anywhere near it so housing is far cheaper.
There's a million and one things I'd like to have: more savings, a nicer house, a better car, more holidays, a bigger family, more time at home. But even with a generous income I still have to make a lot of choices about how and where and why I spend my money and indeed how I earn it.
For example, if I work less I might have more time to do the things I love, but I won't be able to live in the area I want to because it's too pricey.
If I'm getting stressed out by cleaning I can reduce that by having my cleaner do more hours, but that will affect my savings.
Ultimately you need to decide what do you value the most. What's actually important?
If you want to have more money in the bank - people have given you suggestions about where you can make savings.
If you want to see your kids more - people have suggested a 4-day week or WFH or moving.
If you want to be able to be able to be able to better manage your household - people have suggested ways of keeping your home clean with two small kids around.
But your household income and overall wealth is nowhere near the level where you can have shedloads of savings AND a FT nanny AND nursery AND a cleaner AND a husband who doesn't help at home AND do fewer hours AND live in zone 2 etc. We can't always have the things we want - essential though they may seem - despite working incredibly hard.
The people who do have the kind of cash to achieve all of that won't work any harder than you.
The people who work three minimum wage jobs and live in a crappy HMO don't work any less hard than you.
Only you know what you value but you will have to make some difficult choices about your lifestyle, finances, family and work - as does almost every adult in Britain.
