The family is babysitting the Kagans' new baby, Tony, for a night. Tony bonds with Jesse, who lets Tony sleep in Michelle's old crib, lets Tony play with Michelle's toys, and sings Michelle's special bedtime song to Tony, and this leaves Michelle thinking Jesse no longer cares about her. Jesse proves Michelle wrong when he realizes how hurt he's making her feel. Meanwhile, Danny enrolls Comet in obedience school, and it's not making Comet as obedient as Danny would like for him to be.
