Ask most any parent and they will tell you raising a child is a full-time job and then some. Now, a new study indicates that may not be entirely true.The study, published in the Daily Mail, found working moms spend an average of 28 hours a week child-rearing. Of course, that's on top of the 40 or more hours a week they work. The study found on average, working moms work about 13 hours if you combine their job and family responsibilities.

Nine of ten moms in the study said there are days when they are busy from the time they get up until they go to bed. The study also reports working moms get help from their spouse, especially on the weekends.

The study found cooking, cleaning and other chores add up to almost eight hours a week. Another eight hours is spent entertaining the kids. The remainder of the time is split between making beds, washing up, driving the kids to school and activities, helping with homework, running errands, and taking care of pets.

So, what do moms think of the study? A whopping 92% disagree, saying that parenting is a full-time job.
