What's on Eli's Head? And the economic implications of working moms

One of Eli's favorite silly games, besides peekaboo, has always been "What's on Eli's Head?"(WOEH) We would put something like a toy or a bib balanced on his head and he would be so confused trying to reach it until it fell down and he was gleefully surprised to find it. (It's amazing what keeps babies and parents amused). Now that he is older, he can play peekaboo or WOEH by himself. He's discovered it is fun to take everything out of the diaper bag (which we almost never use), and put the clothes on his head, repeatedly, and then crawl around until they fall off. Pretty funny to watch.
In other news, apparently Eli is sort of walking in daycare. Well, taking more than the one or two steps that we have seen at home. The lady at daycare tried to stage a demo this morning, but Eli wasn't cooperating.
On a different subject, the New York Times published an article yesterday by Edwardo Porter, "Stretched to the Limit, Women Stall March to Work." A very interesting comparison of working mothers today with previous years and the economic implications. Basically the bottom line is yes, I am nuts for having a kid early in my career (*gasp*, in my 20s) and that is why more moms today work more years before having kids later and then stay home (which is true for many in my small circle of 30-something+ mom friends). The demands of motherhood and the workplace haven't gotten any easier over the years, and there are still only 24 hours in a day. One researcher compared mothers in 2003 and 1975, and found "employed mothers, on average, worked at home and on the job a total of 15 hours more a week and slept 3.6 fewer hours than those who were not employed." The rate of women participating in the workforce has declined for the past few years (after increasing over several decades), which has all sorts of economic growth implications.
Maybe more employers will finally start realizing the importance of truely family-friendly policies for employee retention and productivity?? Or will more women realize the insanity of trying to have it all simultaneously and continue the trend of working for 10 or 15 years, and then leaving the full-time workforce to have kids in their 30s (or later)? And what will happen to these moms' careers if/when they try to re-enter the workforce after the kids go off to school? How long will it take for employers to adjust accordingly?
