Big Baby, along with Lotso and Chuckles, was once owned by a young girl named Daisy, as was revealed to Woody by Chuckles himself. Among them all, Lotso was the most special to her. One day, during a break at a rest stop, she was playing with her toys when she stopped to have some lunch, after which she fell asleep and forgot them there. They waited day in and day out for her to return to them, but on one rainy day, they decided to make the journey back to her house when she didn't come back for them; however, upon arriving, Lotso glimpsed through the window at her playing with another Lotso. Angered that she had replaced him, he then convinced Big Baby that they all had been replaced and that she no longer loved him and intimidated Chuckles into remaining silent about the truth.
They then hitched a ride on the back of a Pizza Planet truck before being thrown off by a bump in the road and landing in front of Sunnyside Daycare, which Lotso proceeded to take over using Big Baby as his enforcer, due to his considerable size in comparison to the other toys.
Big Baby is a big and strong baby doll, arguably around the size of a real human baby, with a broken eye that hangs loose. With that being said, he is the biggest and strongest toy at Sunnyside Daycare. He carries a bottle of milk around and is adorned with childlike scribbles that resemble tattoos. He doesn't talk; he only communicates with baby sounds (except for one line "Mama?" near the film's climax).
He was Lotso's right-handed henchman, thus making his 3rd in command (if one ignores Ken who is 2nd in command). He is first seen coming out of the bathroom door after Lotso knocks. He is later seen restraining Buzz Lightyear after he escapes from the Caterpillar Room and throwing Mr. Potato Head into "The Box" and shutting him in twice. However, as soon as Woody tells him about Daisy, and after Lotso smashes the pendant that Daisy gave him and pokes him in his stomach, Big Baby retaliates by throwing Lotso into the dumpster, finally having had enough of his lies and abuse. During the credits, he is seen living a happier life at Sunnyside under the care of Barbie and Ken.
Role in the film
Big Baby is first introduced while Lotso is leading Andy's toys to the Caterpillar Room, where the bear assigns them to. Later that evening, after the toys experience a rather rough playtime with the toddlers, Buzz emerges out of the Caterpillar Room and follows some of Lotso's henchmen into their secret hideout, the Vending Machine, where he eavesdrops on the gathered group, but is caught in the act by Big Baby, who throws him into sight of the group. That night, when Andy's toys are imprisoned in the Caterpillar Room, Big Baby separates Mr. Potato Head from the other toys by imprisoning him in a sandbox. The next night, Big Baby stands as a guard while Ken and a reset Buzz (who now serves as one of Lotso's helpers) take roll call to make sure that all the toys are there, then the three walk off to capture Mr. Potato Head after discovering a real potato inside his cell. Once again, Big Baby imprisons Mr. Potato Head in the sandbox outside after Mr. Potato Head kicks Ken in the shin, though this is revealed to all be part of the toys' escape plan.
During the escape, while Big Baby is rocking slowly on a swing and looking up at the night sky, Woody, Buzz (who has now been set to his Spanish mode by the toys by accident), and the other toys across the playground sneak past as they make their way to the garbage chute (the only escape route that the Chatter Telephone has told Woody about) Woody, Bullseye ,and Aliens get separated from the others when one of the patrolling trucks approaches them and sneak past Big Baby but they accidentally get Big Baby's attention when one of the Aliens falls, making him land with a squeak. Big Baby gets off the swing and walks over to the source of the sound, but the toys dive under a plastic sand bucket at the last moment, so that Big Baby finds nothing when he reaches the spot where the toys have been standing. Shortly after, he, Lotso, and the other henchmen finally catch on that Andy’s toys are escaping and go after them.
At the garbage chute, after Big Baby, Lotso, and the other Sunnyside toys surround Andy's toys at an open garbage dumpster, Woody brings up the subject of Daisy and shows Lotso and Big Baby an object he has received from Chuckles during his stay at Bonnie's house: Big Baby's old pendant. Upon catching sight of his old pendant, Big Baby suddenly remembers Daisy. As Woody tries to tell the truth about Daisy to Lotso (who doesn't want anything to do with Daisy) and Big Baby, Woody tosses the pendant to Big Baby, who picks it up to take a look at the token of his lost love and shows that he still cares about her, whom he affectionately refers to as "Mama." Lotso suddenly snaps at Big Baby for loving Daisy again, yelling to him that she has never loved him as he snatches the pendant away from Big Baby, slams it onto the dumpster lid, and smashes it into pieces with his cane. Seeing his last remaining memento of his old owner being destroyed, Big Baby begins crying, and then Lotso hits Big Baby abusively with his cane for thinking like a dummy, causing Big Baby to yowl in pain and the other minions to see the error of their ways. Realizing that Lotso has taken him away from Daisy and fed up with all of Lotso's deceit and tyranny, Big Baby lifts up the wicked bear and throws him into the dumpster, then slams the dumpster's lid on him. The fully redeemed Big Baby then blows a raspberry at Lotso as payback and helps Woody and his friends climb to safety.
During the credits, Big Baby is shown to be having a happier time at a now cool and groovy Sunnyside under the care of Barbie and Ken, the new leaders. At a disco party held in the Butterfly Room, Big Baby, wearing gold diapers (similar to Ken's tuxedo and trousers and Barbie's dress), is seen hugging Ken and Barbie in his arms and happily spinning the couple around in a spotlight.
From Official Website:
- The way in which Big Baby throws Lotso into the dumpster mimics a scene in Star Wars Episode VI: Return of the Jedi, in which Darth Vader/Anakin Skywalker, throws Emperor Palpatine into the reactor shaft of the Second Death Star to save his son Luke Skywalker. This may only be a possible reference, unlike the ones from the previous Toy Story films.
- Big Baby has what appears to be a lazy-eye, which was caused when he was knocked off the truck and landed near Sunnyside. It is also a possible reference to Babyface.
- Before Daisy accidentally left her toys, Big Baby wore a yellow onesie with a matching bonnet. However, when he and Lotso got to Sunnyside, he wasn't wearing it anymore. It is unknown what happened to it; he lost the bonnet when he fell off the truck and also broke his left eye.
- Big Baby's tattoos may have been based off concept art of Ducky, which depicts one drawn on by Sid.
- Big Baby is based on a baby doll that director Lee Unkrich's daughter, Hannah, had when she was growing up.
- In Sweden, he is named Babyface, just like one of Sid's toys.
- Big Baby does have a physical appearance in Toy Story 3: The Video Game, but only a silent cameo on the Sunnyside level for the PS3.
- He is mentioned in the Disney cruise show, Villains Tonight!, when Hades considers bringing Lotso to the underworld. He then changes his mind, saying, "No, he brings that baby with him! Gives me the willies..."
