In a series of firsts, Terra and Joe adjust to their life with the baby at home. The new little parents are exhausted and together they face many challenges, from breastfeeding to giving the baby her first bath. Joe and Terra also take the baby to her first pediatrician appointment to help understand the challenges their daughter may face.

Terra worries about having to take Penny to see a neurologist and struggles with her new role as Mom. Joe hopes a visit from his cousin Sonny will lend a helping hand, but after their task to buy a car becomes an afternoon at the bar, Terra realizes she may need professional help.

Terra still doesn't fit into any of her pre-maternity clothes and convinces Joe to make a get-fit pact. While working out, Joe reflects on all the surgeries he endured as a child and hopes Penny's impending genetics test results won't reveal a similar fate.
