I'm on about double that, but have an insane mortgage (London prices!) so probably take home what you will after housing. DS & I, plus a terminally ill DM but obviously (and sadly) that won't be long term.
Life is very comfortable. I try and be savvy when it comes to 'the basics' so we don't end up with a load of lifestyle creep, and make sure to budget, but am happy to splurge on things that I find 'worth it'. For me, that's some clothes (nothing OTT, the odd designer piece from Vinted and the rest is the nicer end of high street), travel and experiences. We're lucky to travel a lot but it's always economy flights and 'basic' accommodation - we could probably travel less/fancier but it's not worth it with a 5yo!
One of the first things I did when I started earning more was figuring out roughly what I wanted to gift/help DS out with in the future, and worked out how much I need to start investing now to cover Uni/Driving Lessons/Car/House deposit.
Life insurance/critical illness cover is super important if you don't have it already - god forbid something happen to your DH, you don't want money worries on top of that, especially once you settle into a slightly 'nicer' way of life! I'd also look at a really healthy emergency fund for if anything happens to his job and he struggles to find anything that pays that much!
Private school is within reach (I'd struggle to say that with 2 kids though) but we have a great state school and DS is thriving there. The money does help with extra curriculars/clubs/activities and will pay for tutors when he's older.
We have a part time housekeeper, though this is a necessity because of DM (I was drowning in housework/caring/parenting/full time job) - I think if that weren't the case I'd probably 'just' have a cleaner. Very grateful for anything that means I don't have dust regularly tbh!
Eating out is really regular for us, as are days out. I try and be 'savvy' and use discount codes/apps/loyalty programmes as much as possible, but we still spend a decent chunk every month on it!
IME, there will be 'costs' relating to have a job with that salary. Mine are decent clothes for presenting/office visits, the expectation to put my card behind the bar for drinks on a team night out when expenses won't cover it etc. Don't argue over these - sometimes it just needs doing.
Oh... and I do have my dream, diesel guzzling, constantly breaking down Land Rover Discovery - no regrets 😂 I did get it a few years old though, and will downgrade to something more reliable/boring when my lease is up.
