Barney: I wouldn't have to choose between dating and having a family, hell, I could bring the kids on dates!
Ted: And a broken home? Um, what's that? Our kids will never know. Cause we're never gonna split up!
There are all kinds of families. Some characters have a mother and a father. Some may have a stepparent (with varying levels of goodness and wickedness) thrown in. Some were Raised by Grandparents. Some have two mommies or two daddies. Some have a single parent.
Bob, on the other hand, is raised by his mother Alice, and Charlie. No, Charlie isn't Bob's father, nor is he romantically involved with Alice. He might be her best friend, or perhaps her brother. Either way, he's every bit as involved in Bob's upbringing as she is; he'll drive him to school, cook him dinner, punish him when he acts up, and come running if he needs help. It doesn't matter that Charlie and Alice aren't a romantic couple; Charlie is, for all intents and purposes, Bob's father.
Note that this doesn't need to involve two characters of the opposite sex, or even only two characters. Platonic Co-Parenting is simply about two or more people raising a child together, without romantic entanglements. It's quite common for this sort of family to also to be a blended family; Charlie helps Alice raise her son Bob, and she helps raise his daughter Danielle. It's also possible for none of the parties to be biologically related; perhaps Charlie and Alice found Bob abandoned when he was an infant, and decided to take him in. Either way, there's often a message about how a Family of Choice is just as important and real as one dictated by blood, if not more so. (If Bob's biological Disappeared Dad shows back up, expect him to call him out, pointing out that Charlie did more for him than he ever did.)
Depending on the story, Alice and Charlie might undergo a Relationship Upgrade... but even if they don't, if they're not related, it's a pretty safe bet that a good chunk of the fandom will want them to. Odds of an official upgrade are actually pretty low; a Last-Minute Hookup might occur, but most of these couples are relegated to Just Friends status, sometimes with the occasional Ship Tease. (If Alice is Alan or Charlie is Charlotte in this particular scenario, or if there's more than two of them involved, the chances of an actual upgrade are even slimmer.) If the creator really wants to hammer in that the setup is strictly platonic, there might be an Incompatible Orientation involved, or they might be sure to place emphasis on the "heterosexual" part of Heterosexual Life-Partners. One or both parties might also be involved with someone else, often with the other as a Shipper on Deck. Some works might have the characters actually consider dating, before concluding that they're Better as Friends. (Not that any of this ever stopped the shippers...)
Not to be confused with a pair of Amicable Exes raising their children together. Alice and Charlie can't have been romantically involved (or if they once were, it needs to have been long over by the time the kids came into the mix).
With blended and non-nuclear families becoming more commonplace, this pops up in Real Life, too.
Compare Like a Son to Me, Parental Substitute, Family of Choice, Honorary Uncle, and Happily Adopted. May be a reason for Has Two Mommies if the same-sex parents aren't a couple. Also see Amicably Divorced for when divorced parents are on good terms and co-parent their children.

- A similar example as above in Circumstances of an Unexpected Trio series by Musicangel913, though they are also raising Draco along with Harry, who was given to them by Narcissa after her husband was tortured into insanity and learning that she'll be killed soon as a liability for being more loyal to her family than to Voldemort. When Harry asks Sirius how come he and Lily never got together romantically, Sirius admits that both were still holding a torch for their deceased partners (James for Lily and Marlene for Sirus), and their attempts to come together due to the stress of raising the two boys and the approaching dates of their dead lover's anniversary lead them to admit they were Better as Friends, which in the long run helped their family unit.

- In the first book of the Earth's Children series, Ayla and Uba are raised by their mother Iza and uncle Creb, who live together after Iza's mate died (he was an abusive jerk, so they're all well shot of him).

Later in The Clan of the Cave Bear, they all help Ayla raise her son, Durc (no man wants to mate Ayla because she's considered unattractive by Clan standards, while Durc's biological father is the Big Bad Broud, who unknowingly got Ayla pregnant after raping her and wants nothing to do with Durc).
- Forbidden subverts this. At first, Maya and Lochan do this, having been Promoted to Parent a long time ago. Then it becomes obvious that the setup isn't really platonic.

- In one plotline of The Bold and the Beautiful, Thomas (who, it must be noted, is batshit crazy) attempts to use his son Douglas as a means to get to Hope, since she has a soft spot for the kid, and Douglas' biological mother has died, causing him to see Hope as a Parental Substitute. Hope eventually realizes what's going on, but feels she can't abandon Douglas, so she tries to persuade Thomas to make her his son's legal mother without actually becoming romantically involved, intending to then sue for complete custody. This being a soap, Thomas being Thomas and Hope being Hope, this leads to an extremely convoluted Gambit Pileup, with lots of I Know You Know I Know to go around.

Tommy and Chuckie decide to be Spike's dads, while the twins take on the role of his "Uncle Bill and Aunt Harriet".
- Steven Universe: After the death of his mother Rose, Steven is raised by his father Greg and Rose's war compatriots the Crystal Gems.
