Season 10, Episode 7 - "Raising Willa"
When Roz is called out of town for a radio conference, the guys are forced to take shifts in helping Alice with her newborn daughter, Willa. Bulldog is tired of having another baby to take care of so he hands the job to Gil. Gil does the same to Kenny, who leaves Noel with the chore. When Willa won’t stop burping, Noel fears something is wrong and the four of them are forced to work together to resolve the crisis. Luckily, Alice’s instincts kick in and she sees herself as a mother for the first time. Roz returns shortly afterwards, revealing that she was too worried about Alice to care about a conference, and has been sitting at the end of the road all this time. The guys, of course, are mortified.
