M.,
Grin and bear it if you knew about it before you married him or they were born.
Introduce little things along the way.
My DH is currently setting up DS to be a Daddy's boy by working all the time and doing homework, and when he wants attention, doesn't answer until after 3-10 asks (yes, my DS will ask for Dada's attention that much and finally get it after calling him by his GIVEN name (what I have to use most times to get any of his attention also)). He won't go to DS when he is in distress until I am nearly there, and then pick him up as if I were the worst Mom and comfort him and not let him go. It doesn't happen often, but it happens. DS adores and worships DH and he knows it.
DH knows day-to-day and makes a point of telling me I don't do enough, to boot. I am coping with 11+ years of bachelor living and no place to put things, and he expects M. Stewart. He also somewhere along the line expected me to learn how to cook.
Sounds like I'm griping back at you - but all I am doing is illustrating that if that is what you had before the babies, babies don't change anything.
He has to SEE other men modeling what you want him to do. It's sad, but a lot of people weren't taught to be self-motivated by the school systems we have. That's only one part of the dilemma.
If and when he sees the modeling, he has to agree with it and see also that he is capable of doing the same for his children.
Where you're going to get that kind of modeling? Find a home school community. It's the only place I can think of. Another would be a very Christian household; but even then, you don't necessarily have someone who is willing to open up and share.
Look into Waldorf education for your children. Teach them as BEST _YOU_ can.
I have a lot of other stuff, but my own DS is waking from his nap and I'm off and running,
Good luck, email me if you wish/want more,
M.
PS: mine knows what to do. he's not helpless. He just plays the part. He's from a family of 9.
