The Sunday Question: How Do You Divide Domestic Chores with Your Spouse?

In just a few months, I’ll be enjoying maternity leave.  It’ll be a treat to have a few months off since with my first child I went back part time when he was just six weeks old.  Since I never really had the time to be home, my husband and I have split laundry, cooking and cleaning pretty evenly from the beginning.  This time I wonder if it will be different since I’ll be home for a stretch and might feel obligated to pick up more domestic duties.  How have you managed to share the household workload with your spouse?  Did it change during maternity leave–and more importantly, if you did go back to work how did it shift again?  Any advice you can offer will be greatly appreciated!
