I am always impressed at couples who have the household/parenting balance all figured out, so that each person feels like it's balanced and fair! It's something we work a lot on in our household... Charlie is 3 1/2 and it's taken until this year that things have become relatively balanced, I think.

When Bee got pregnant with Olive, I started doing a lot more of the parenting related tasks... and in the past year or two, I've started doing taking over more chores. It's been a journey... I've written a bit about it on the blog:

Has imbalance in the amount of household/parenting work you and your SO each do caused friction in your relationship? How have you guys managed that?
