If you want kids so bad and for them to have the best chance... you need to get your head out of the butt and start thinking logically.
Start saving.
I say this with respect but your dh can't be your whole source of income and support. You need to start paying things proportionally as well.
You will not be able to pay 50/50 and maintain the same lifestyle on your salary once you have kids. Everything associated with parenting costs money, nursery fees just the tip of the iceberg.
Equipment, food, bill increases, clothing, clubs, activities. Are you going to be able to pay 50/50 for everything little tiny they need?
You say that you'll go back part time but what if you have difficult birth? Or get made redundant? Or have a bad sleeper?
Is your dh going to do night feeds, sick days, half terms? Or will it be you looking after them because your job can be more easily sacrificed?
You seem really naive about what having a kid actually entails and even more unaware of what the pressures financial and otherwise does to a marriage.
This forum is full of women that swore blind their marriage and dh would be different but life changes people and you need to be prepared for the worst if you're bringing kids into it.
You need a damn pension and some savings first or you will end up shits creek with an armful of kids and no plan for your own future.
If you cba to work and just want kids, fine I respect that too but just be smart....there's no guarantees.
Also have you though of a career working with kids ? That's something you could work on in the meantime.
