Sense check

We are in our mid 30’s with one baby starting childcare soon.
I earn $280 K pa by performing higher duties, my base salary is around $215K. I have a good chance of continuing at the higher salary but it’s not certain.
My husband earns $235 pa with a bonus last year of $72K.
Both salaries are excluding superannuation.
Is a mortgage of $1.8 - $2 million (depending on the sale price of our existing home) for a $3 million PPOR stretching what we can comfortably service? It’s a very scary proposition in a softening market with potential further interest rate rises, so looking for some sage advice! Thanks in advance.
