No we are not all born independently wealthy. But most of us start out single earning a living, independent adults with interesting lives (interesting here is capable of earning, living independently) have interests, hobbies, friendship groups, plans, aspirations and dreams. We meet, we flirt, we laugh, we win people over with our charm and wit, and we have sex. Then family life becomes a reality. When men earn and have lives within the public domain and women find themselves relegated to just the home, a split takes place. Read Plato, read anything even! and the gap in everyday lived experience, realms of responsibility, interests and goals can seem like a vast chasm. His goal: get to work on time, talk to rob in accounts to claim back expenses, get tickets for Saturdays match, her goals: get breakfast down toddler before baby wakes up, get out of the house without having a nervous breakdown and take cat to vet. Unless all of these responsibilities and roles are shared it can leave a couple seemingly living in very different realities with not much empathy, understanding or respect between them and even less to talk about and no desire to engage.
The only other way in which it can work is if both people can make the leap of imagination and fully try to comprehend the others experiences, sacrifices, and feelings. More and more this doesn't happen because women are expected to work, but also to do everything else (because men have never comprehended how much work women do) and also because we live in a consumer society where we have no attention span and no sense of time/space. Everything and everyone is expendable and replaceable, or at least we can substitute with any number of modern distractions such as tv, media and porn.
I'm sorry OP, if talking doesn't work, its because he is losing respect. Can you gain it back? Maybe but only if you can get his attention. Up to you, but with two very young children it might be worth trying at least in the short term. Long term, well its not great and no I wouldn't put up with it. Instead of waiting to be noticed, leave the kids with him and make a plan to do something exciting without him. He might notice you are missing!
