As a parent of a 4 year old and 3 year old who has to travel ~20-40% for work, I can assure you that the flexibility you have has quite a lot of value. Sounds like your kids are perhaps near same age since you mention both having to attend IEPs and that you’re paying childcare and kids aren’t in school.

It definitely sounds like you could make more elsewhere. But I’d agree that it sounds like it would be easier to make that move in 1-3 years or whatever it is until kids are in full time school.

You’re not hurting for money, you’re saving plenty for retirement, and delaying a move to higher income a little longer (combined with no longer having daycare payments) will allow plenty of extra income to achieve your additional goals.
