One for My Baby

 is a quest in Fallout: New Vegas.

Quick walkthrough
Talk to Boone, who is located at the top of the Dino-Bite Gift Shop at night. He will mention his wife during conversation. Offer to help. Ask No-Bark Noonan about Boone's wife. He will mention the Dino Dee-lite Front Desk. Sneak in at night and obtain the Bill of Sale from the safe behind the desk. (go check bugs if your havieing trouble asking her to take a walk) Ask Jeannie May Crawford to see what is in front of the Dinosaur. Put on your beret and lead her there. Go back to Boone. After you complete the quest you can ask him to join you and he becomes your companion.

Detailed walkthrough
1. Go to Novac between 9 PM and 9 AM. Find the giant dinosaur and enter it. Once inside, head up the stairs and go through the door at the top. You should meet a man named Boone. Talk to him about his wife and you will receive the quest to find out who sold his wife off to slavers so he may kill them. He also gives you his beret to wear as a signal to fire on the person you bring in front of the Dino.

2. You are then given the task to talk to select inhabitants of Novac. Luckily, you only need to talk to one of them in order to progress in the quest. This person is No-Bark Noonan, an older man that seems a little out of his mind. You can find his shack behind the motel. Talk to No-bark about Boone's wife and he will tell you about strange business in the motel lobby. (If you have a high enough speech level you can finish the quest without evidence. Just talk to Boone after talking to No-Bark Noonan)

3. Head to the front desk of the motel and once inside check behind the counter to find a safe in the floor. This safe is locked and will require you to either lock pick it (easy skill) or pickpocket the key from Jeannie (there is no loss of karma). Inside the safe you will find a note titled Bill of Sale. This document tells of how Jeannie May Crawford sold Boone's wife off to slavers.

4. Now you have the evidence so confront Jeannie at night and ask her to take a stroll with you in front of the dinosaur. Once in front of the dinosaur put on the beret and Boone will kill Jeannie and your job is done.

5. Head up to Boone. He will ask you how you knew it was her (this is where getting the evidence comes into play) and you tell him about the bill of sale you found. If you did not get the evidence you can use speech on him but if that fails he may try to kill you or he may get angry, snatch his beret back, and say that he doesn't ever want to see you again (thus no option of his being a companion, obviously). If you told him about the evidence you can keep talking to him and make him become your companion. Upon joining you, you will gain the Spotter perk.

After accepting the mission, you can go talk to Manny and get him to walk in front of the dinosaur where Boone will kill him, whereupon you can get some good loot from Manny's corpse (including his beret which carries a +5 crit.hit) without getting any negative karma, though Boone will be angry at the lack of evidence as mentioned above and not be your companion unless a speech check is passed (55). However the same +crit beret is given as a reward for completing the quest correctly (sending Jeannie May). If this alternative is chosen, the side mission of clearing out the building to the west should be completed and turned in first.

Bugs

 * If you cannot get Jeannie to follow you, try the following solutions:
 * Use the Wait function to move the in-game time between 9PM and 9AM. Suggest moving it to a comfortable time between then. Midnight seems to work well. (Confirmed. You may not actually be able to confront Jeannie, but if you talk to her during this time duration an option will appear in the dialog asking her to follow you to the front of Dinky the Dinosaur.)
 * Change your tracked quest and fast-travel out of the town. Return, retrack the quest, and attempt to confront Jeannie
 * Try speaking to Jeannie at night while she is at her house, or while she's on her way home or in the Motel Lobby.
 * Speaking to Boone, while on the quest, as he heading to the dino head will cause him to become stuck. Making it not possible to ask someone to head in front of the dino.
 * Obtaining the evidence before speaking to any NPCs in Novec will result in a quest completion for the optional objectives.
 * Obtaining the evidence before talking to No-Bark will result in a quest completion for the optional objectives.
 * If you talk to No-Bark Noonan and before meeting for the first time Boone he will confront you as if you already know him, skipping dialogue and interaction with the character that would have been available before you accepted the quest.
 * Having a higher than typical amount of reputation in Novac can result in the quest not beginning. (Not really a bug, as Boone states during the start of the quest that he trusts you had nothing to do with his wife because you're new to the town)
 * Disputed: Quest completed while Idolized in Novac, no issues encountered.
 * Binding Boone's Beret to a Directional Pad key may result in a console crash. (CONFIRMED)
 * Sometimes the evidence will not appear in the safe, halting your progress unless high enough speech is available to convince Boone without it.
 * After completion of the quest, if you have Boone join you as a companion he is supposed to gain a set of armor, this may not happen. (Boone continues to wear Merc Grunt armor until the completion of the I Forgot To Remember To Forget quest.)
 * After the quest is complete, Boone clearly takes back his NCR beret, but the player can still find it in their inventory. --Needs Confirmation, Boone gives you a 1st Recon Beret as a reward for the quest, and takes back his. Are you sure thats not what your seeing? (confirmed, Boone gives you an alternate 1st recon beret as a quest reward as well as ~150 caps.  The beret you use to mark the target in the quest is named "Boone's Beret" After he takes it back it is renamed "1st recon Beret" in his inventory and he gives you another one as part of the quest reward, watch your notification area in the top left, it says "Boone's Beret removed" then "1st recon beret added".
 * Starting the quest without first talking to the hotel manager about heading over to the gift shop will cause Cliff to not take over has hotel manager and cause you to be unable to access the hotel room (unless you get the key before having her executed) -- Disputed: I was able to loot the key from her body after Boone killed her.
 * If Boone's beret reaches 0% condition, it can be repaired with other berets. (Confirmed Xbox 360)
 * Sometimes, if you send Jeannie but don't wear the beret, you may not be able anymore to repeat the operation. However, Boone will consider quest is finished if you speak to him, so you can have it as a companion while Jeannie is still alive.
 * On rare occasions, NPC's (Jeannie's?) AI walking script will stop working. As a workaround, the player must push the NPC to the location to complete the quest. -- Confirmed
 * The best way is talk to Jeannie outside when she leaves around midnight. I always get the option to follow.
 * If you ask the wrong person to go in front of the dinosaur then talk to them about something else,they will become stuck and they do not return to their original location. After this you are no longer able to take Jeannie May Crawford in front of the dino, rendering the quest broken.

Trivia
"One for my baby (and another one for the road)" is the title of a song by Frank Sinatra. It is a song about sorrow and having lost something dear to you.
