What do you do all day? / Amy Scheibe.

Enhanced descriptions from Syndetics:

Amy Scheibe's debut novel is a fresh, funny, witty take on the magic manic days of young motherhood. Her Jennifer Bradley is a thoroughly modern mommy--a former club kid who is married to the man of her dreams and who quit a fabulous job as an antiquarian objects dealer to raise her two children: Georgia, a very advanced age 4, and baby Max. But it's alarmingly easy to spin a stay-at-home mommy's world on its axis--and Jennifer's is whirling. If it's not her mother-in-law on her tail to expose her precious grandchildren to a better element (not to mention pointing out that dangerous concrete floor in their loft), it's her husband Thom announcing he'll be on the road to Singapore for the next who-knows how long. And is this really the right time for her dad to announce that her mother isn't exactly who Jennifer thinks she is? Or for the ex-boyfriend--aka the Adult Child Actor--to come back on the scene? An American answer to Alison Pearson's "I Don't Know How She Does It," "What Do You Do All Day?" is a sparkling, lovable novel for mommies of all kinds--whether in the trenches or out on the hustings.
