Do you ever feel like the only parent who nags?

I do. It's almost always me reminding the kids to do their homework, eat their fruit and vegetables, take their vitamin, get ready for school, take showers, brush their teeth, etc. etc. I admit that I need to scale back on the nagging, at the risk of taking on too much responsibility for my kids (and/or turning into mere annoying white noise that they want to ignore). But at the same time, these are things the kids NEED to do, and I have moments when I feel resentful that I am cast in this role much more than my husband is. This isn't meant as a dad-bashing post at all... my husband is an awesome father and does many things for my boys, including disciplining them when they misbehave on his watch. It's just that more of the things he does tend to be un-naggy in their eyes, like playing ball, doing silly dances at bedtime, taking on household chores when the kids are playing on their own and, of course, working very hard full-time so we have a regular salary and health insurance. I have fun with my boys too, of course, but I'm just wondering why I so often feel like I have to be the more serious parent. Other friends who are mothers have said they feel the same way. Is it simply because we're often around our kids more on a day-in, day-out basis, and therefore have a better grip on responsibilities they need to take care of? Is this just a female thing? What might I do to even out the balance and feel less like a stick in the mud? My husband and I did have a talk in which he agreed he would help more in this department, but it still seems to fall largely to me.
