Money minded parent

How do you deal with your own mother when she always talk to your husb without being mindful / sensitive with her words cause she felt that your husb isn't good enough for you in terms of job and income. She will tell u "find a rich husb then you don't have to work lor" whenever you educate your LO in the morning that "mummy has to go work" she's the only main caregiver for nw since both parents have to work.
