Look Who's Talking Too is the 1990 sequel to director Amy Heckerling's 1989 comedy Look Who's Talking. The film stars the original cast members John Travolta and Kirstie Alley as James and Mollie Ubriacco, the parents of Mikey (voiced by Bruce Willis), a toddler coping with the newest addition to the family, baby Julie (voiced by Roseanne Barr). In addition to this, he is having trouble using a potty, and the unorthodox advice he gets from his playmate, Eddie (voiced by Damon Wayans), doesn't make his problem any better.
The movie picks up with the now married Mollie (Kristie Alley) and James (John Travolta) having sex and Mikey (voice of Bruce Willis) getting scared. Mollie and James tell Mikey that he's got to be potty trained. Mollie discovers she's pregnant again (this time a girl) and James is working diligently. Mikey learns that with his little sister, Julie, on the way, he has to be a responsible big brother. When Julie is about to be born, her umbilical cord gets caught around her neck, putting her in distress. She is born through a c-section and is taken to the nursery area for observation.
When Julie meets Mikey, she is unimpressed, while Mikey quickly begins to resent his sister when his dreams of being a responsible big brother don't match the reality. Meanwhile, Mollie's slacker right-wing brother, Stuart, comes to stay, to whom James takes an immediate dislike. This, combined with James being pressured into taking a demanding piloting job arranged by Mollie's parents and his belief that Mollie is too protective of Mikey, causes several arguments between the pair which eventually lead to James leaving. Mikey is upset about this and, believing he has left because of Julie, tears up one of his sister's stuffed animals. James occasionally hangs out with his kids (including scamming their way into a movie theater) and has fun with them. Following a burglary, Mollie's friend Rona moves in with her and she soon forms a connection with Stuart.
Following the 'death' of her beloved stuffed penguin (whom she named Herbie), Julie decides to learn to walk and leave. Later, Julie manages to walk to the sofa without support. Mollie sees this and is initially excited but then saddened that James isn't there to share the moment. As he watches Julie sleep one night, Mikey realizes how badly he's treated her and resolves to change his ways. Mollie decides to win James back and dresses sexily for him, but he isn't interested. As the two bicker, Mikey uses the toilet for the first time and calls his parents, who are immensely proud of him and share a tender moment.
One night as James prepares to fly, Mollie watches the news and learns that storms are all around the area. She goes to get James before he takes off, leaving Stuart with Mikey and Julie. She catches him and tries to persuade him not to take off, just as the control tower cancel the flight. The two then makes up. Meanwhile, a burglar (presumably the same one who also robbed Rona) breaks in and runs when Stuart comes in with his unloaded gun. Stuart pursues him having forgotten about the kids and completely oblivious to the fact that he left paper on a hot stove which quickly causes a fire to start. Mikey doesn't panic and takes charge, pushing Julie out of the apartment to safety. Stuart and the burglar run into James who subdues the thief. Mollie and James soon find out the kids were left alone and spot the fire in the apartment, only for Mikey and Julie to emerge from the elevator as the two prepare to head in to save them. James then puts out the fire before it can cause too much damage.
The next day, James, Mollie, Stuart, Rona, and Mollie's parents attend a barbecue, where Julie asks Mikey why he saved her when they're always fighting. Mikey tells her that for as much as they get on each other's nerves, they're the kids and should stick together since the grown-ups never make any sense to them. The two then walk off hand-in-hand.
