Andrew and Lauren have just found out they're going to have a baby, and are finding it difficult to follow rule number one keeping it a secret. Suddenly switching to decaf, becoming a teetotaler at cocktail parties and going to the OBGYN prove to be difficult to keep from family and close friends.

Andrew and Lauren succumb to pressures of reorganizing their lives. They realize changes are inevitable - donating Andrew's beloved hockey table to make space, trading in the Mini Cooper for a mini-van, and updating an expired license - no matter how much you love the photo. Lauren is experiencing strong cravings and almost jeopardizes her driving test with an ill-advised u-turn into a drive-thru hamburger joint. Eric and Julie are also preparing to welcome their first child by practicing their parental skills with the help of a toy doll. Meanwhile, Cooper moves in on a newly separated married man by flirting with him at a funeral.

Andrew is overwhelmed by the impending costs of having a baby and looks for ways to save... at Lauren's expense. To offset the extra costs, he takes on additional landscaping jobs with Danny's help, despite the fact neither is equipped for manual labor. Meanwhile, Lauren is feeling like she's not getting through to the students she counsels and contemplates leaving her job. When she's pushed over the edge by a student, she leaves work early and heads to yoga class, where she finds Julie and Cooper, each of whom chimes in with an opinion on whether or not she should quit. Ultimately, a chance encounter with a student outside of school helps her come to a decision.

Andrew and Lauren are quickly discovering the pros and cons of being pregnant, including the things that get in the way of intimacy. A definite plus for Andrew, though, are Lauren's highly noticeable "pregnancy" breasts, which also prove to be the object of attention for the students she counsels. On the downside, Lauren's sex drive has diminished and Andrew worries they won't have time to be intimate once the baby arrives. Heartened by his concerns, Lauren makes several attempts to get "in the mood.

An ordinary trip to the mall for makeup becomes extraordinary when Julie's water prematurely breaks, sending her into labor but not without her cosmetics in tow. While Eric rushes home from a business trip to be present for their baby's birth, Julie enlists the help of her friends, Andrew and Lauren, who abruptly abandon their weekend getaway - while Danny ensures that their hotel, spa appointments and romantic plans do not got to waste. Having read every book on pregnancy he could get his hands on, Andrew offers Julie some valuable, if not humorous, advice while she's in labor. Meanwhile, a less than thrilled Cooper reluctantly agrees to capture the birth on video.

Andrew and Lauren are in disagreement over the importance of breastfeeding; Lauren isn't convinced it's necessary, while Andrew is absolutely adamant about it. He claims being a breastfed baby is what has made him the success he is today. That is, until a visit from his mom exposes the truth about his upbringing. Meanwhile, Julie and Eric struggle to reconnect after the birth of Baby Perry, and Cooper falls for a handsome, model-perfect mall employee whom she mistakenly thinks is all brawn and no brains.

Lauren shares the news with her co-workers that she's pregnant, and she's determined to prove it won't have an adverse effect on her job. As she begins to experience the byproducts of pregnancy fatigue and forgetfulness Andrew lovingly picks up the slack. Ultimately this gets them both into trouble when he inadvertently advises a student to put off college. Meanwhile, Julie and Cooper discover the only thing they really have in common is Lauren.

Today is Andrew's birthday. Everyone has gathered to celebrate this special day. Even Andrew's old college buddy is there to celebrate. But the only problem is that Andrew doesn't like him - at all. Sadly, this day will turn for the worse when some of the biggest secrets are gonna be revealed.
