Weesazz - I've posted earlier on and I have a willingly helpful DH, however, I think if you've had a pattern in your relationship before kids whereby the bloke did hee haw and you picked up all the slack, you can't expect them suddenly to change when you have kids.
They will not see the need for change and will continue being lazy unless you tell them otherwise.
Ideally, you need to prep them before the birth (e.g. after the baby is born you'll need to do a, b and c) and then once the baby arrives, keep them to it, remind them, ask them to do stuff. Don't get peed off when they don't do what you think they shoudl be doing, treat them like an idiot, assume they have the memory of a goldfish and simply ask them, and keep asking them until eventually you have them trained.
Some men (like my DH) love the family life and want a partnership, others want their mothers cleaning up after their arse all the time, you have to decide what you want, discuss it with him, tell him what you're not happy with and then get him to do the tasks you do.
He will forget (intentionallly..) and not do things, do not lose the plot when this happens (he's hoping you'll get peed off with him not doing things or doing it wrong that you'll stop asking) keep asking/reminding him.
You now have 2 children, but you need one of them to be a grown up - the training has to start now....
