Mark Nielsen told us that in another draft of the animated movie, Bo Peep had been waiting around in the antiques store, hoping to be bought so she could impact another kid, similar to how Andy’s toys are now Bonnie’s toys.
That’s a totally different spin on the character we see in the final draft, as Bo Peep is tougher in that version.
She no longer hopes or wishes for a kid and wants to maintain her current freedom to move and roam and not have to play dead when people are nearby.
If she had still been in the antiques store, hanging out with the forgotten toys who are living there, she may not have been as tough or liberty-minded in the version Annie Potts voiced for the big screen.
