Jamie stumbles upon a strange cure to Mabel's crying fits, while Paul valiently tries to catch a few winks before an important meeting with a Belgian distributor.

The search for a preschool for the three-week old Mabel cannot begin soon enough, but has to compete for attention with the coupon fraud trial of Uncle Phil, and an odd caper involving Jamie and Ira.

Jamie is reluctant to stop breast-feeding exclusively, but she knows it's time for the baby to learn to feed from the bottle, while Paul is excited to be able to feed the baby for the first time.

It's the first plane flight with the baby and Paul and Jamie take separate planes--they're told it's not uncommon for new parents to do to avoid orphaning a baby in the event of a tragedy.

Meanwhile, Jamie's looking forward to a break from mothering, yet she ends up mothering everyone.

When Paul and Jamie feel that their current therapist, Sheila, isn't quite helping out, Paul and Jamie see another therapist, Sydney.

Meanwhile, Paul grapples with how to get his father to stop suffocating Paul socially.

Jamie discovers that Paul was married before--if only to get an old Russian woman U.S. citizenship. Jamie's upset that she is, indeed, the second Mrs. Buchman. Meanwhile, Paul is an umpire for his father's senior-citizen baseball game, and a fight erupts between father and son over a call.
