AITA for kicking my little brother out over a prank?

The shock, the tears, the betrayal—it’s a scene that could unravel any parent’s nerves. When she kicks him out, her family calls it an overreaction, but the sting of that moment lingers.

This Reddit story dives into the raw emotions of parenthood and the limits of teenage antics. The 25-year-old mom, pushed to her breaking point, faces a tough call: was her reaction too harsh, or did her brother’s prank cross an unforgivable line? It’s a tale of trust, consequences, and the fierce instinct to protect a child, pulling readers into a heated family drama.

‘AITA for kicking my little brother out over a prank?’

Me (25F) and my Husband 'Marcus' (28M) have beautiful 2 month old daughter. Background: About a year ago, my little brother 'Jacob' (17M) came to stay with Marcus and I. My Mom said that she and Jacob were constantly fighting, so Jacob asked if he could stay with us until he goes off to College. I was a bit hesitant at first, but Jacob is my brother and I wanted to help him out.

For the past year everything has been going fairly well...until yesterday. Marcus was at work while Me, Jacob, and my daughter were all at home. I asked Jacob if he could keep an eye on my daughter for a few minutes while I was in the bathroom. After I walked out of the bathroom, I saw Jacob playing with my daughter.

He was at the top of a long staircase, before I could blink, Jacob stumbled and my daughter came barreling down the stairs like a rag doll. I started crying hysterically and bolted over to the bottom of the stairs. After I got a closer look, it turns out that it wasn't my daughter, it was one of my nieces baby dolls wrapped in my daughter's blanket.

My mind was blank, I looked up and saw Jacob cracking up, saying he 'can't believe that worked.' I snapped! I started screaming at him and told him that he was 'beyond f**ked up!' Jacob tried to calm me down, he said it was just a joke and that my daughter was safe and sound in her room.

I was inconsolable at this point, I told him to just pack his s**t and get out! Jacob started crying, he begged me to let him stay and said that he didn't mean any harm. I called my Mom and told her that she needed to come pick up Jacob, or he's gonna be on the streets!

My Mom came and got Jacob, but she later called me and said that I was massively overreacting. Even Marcus agrees with my Mom, he says that Jacob is a dumb teen and should be given a second chance. Now that I'm in a calm state of mind, I'm starting to doubt my reaction, and I'm wondering if I went too far. AITA?

Parenthood flips a switch, turning even the calmest souls into fierce protectors. The original poster (OP) faced a nightmare when her brother Jacob faked dropping her infant down the stairs. Dr. Laura Markham, a parenting expert, notes, “New parents are wired to react intensely to perceived threats to their child’s safety—it’s biological” (Aha! Parenting). OP’s hysteria and decision to evict Jacob reflect this primal instinct, amplified by sleep deprivation and bonding hormones.

Jacob’s prank, though not malicious, ignored the gravity of OP’s new role as a mother. His laughter and dismissal of her distress show a teen’s immaturity, clashing with her heightened parental sensitivity. Meanwhile, her mom and husband’s defense of Jacob as a “dumb teen” minimizes her trauma. A 2023 study from the Journal of Family Psychology found that 72% of new parents report increased conflict with family over boundary violations (APA Journals). This prank crossed a clear line.

Markham suggests parents set firm boundaries while fostering understanding. OP could have a calm talk with Jacob, explaining how his actions triggered her fear. His tears and apology hint at remorse, but trust needs rebuilding. Allowing him back after a cooling-off period, with clear rules against pranks, could balance accountability and forgiveness. OP should also discuss her feelings with her husband to align their stance, ensuring her emotional needs are validated.

For moving forward, OP can use this as a teaching moment. Markham advises guiding teens toward empathy by discussing consequences. Jacob, nearing college, needs to learn that pranks affecting others’ safety aren’t harmless. A family meeting to set boundaries, paired with an apology from Jacob, could mend ties. OP’s reaction was human, but a measured approach now can preserve family harmony while protecting her peace as a new mom.

Here’s the feedback from the Reddit community:

The Reddit crowd swooped in like a protective flock, dishing out support with a side of righteous indignation. Here’s the unfiltered scoop from the community, crackling with empathy and a few sharp jabs:

pinkie18 − NTA - he made a dumb decision and he’s going to learn there are consequences. And I’m sorry you had to live for even a second thinking your daughter was flung down the stairs.

Standard-Wonder-523 − You are absolutely NTA for kicking him out. Gee, I can't imagine why your mom is having problems living with him. Maybe after a month or two consider offering him a chance to live with you again, if he keeps in mind that your child's safety is not a joking matter to you. But absolutely, he can deal with a few months of living at home with your mom again so he can realize that his actions can have consequences even if no one gets physically hurt.

FuriousPug − NTA. I have an infant myself, and understand that you are: 1) Sleep deprived; 2) filled with bonding hormones and 3) running on mostly adrenaline. Jacob is young and couldn't know how awful a prank this was, and will likely understand your reaction if he ever becomes a father. Hopefully now that you've had time to reflect you are in a better state of mind and can forgive Jacob, but your reaction in the moment was a natural and very human response.

Aquaticfilly0 − Ask Marcus and Jacob to explain the joke to you. Ask them to explain what's so funny about pretending to kill your child

[Reddit User] − NTA It’s not funny. These dumb jokes and pranks that these silly teenagers keep playing are not funny. You showed him that there were consequences to his actions. I bet the next time he tries to play a dumb ass prank he’ll think twice about it. He needs to learn that he can’t play with everybody because everybody’s not going to be playing with him.

[Reddit User] − NTA. Pranks are funny, or should be. They shouldn't leave a young mother in terrified hysterics. You did your brother an enormous favour and he put you through unnecessary trauma. Obviously, whether you decide you can forgive him is up to you. In your place, I wouldn't as long as he's being defended by the 'boys will be boys' BS instead of apologizing profusely.

TemperatureMore5623 − Wtf is wrong with people? I had a “prankster” friend in high school that always took things too far like this. No one else thought it was funny, but somehow he always did. He literally pranked a bunch of people at a party by PRETENDING TO HANG HIMSELF IN THE BASEMENT.

He rigged this whole setup to where it LOOKED like a noose and he was hanging, except he was still able to stand with one foot on a large brick sticking out of the wall. So of course, someone came down to the basement for more drinks and really believed they found their friend lifeless and dead. Turns out the guy who found him pulling his prank had actually found his older brother WHO HAD ACTUALLY HUNG HIMSELF, dead.

As a child. The guy who “found him” immediately started throwing up and screaming this… just… CURDLING scream, it was f**king awful. And the prankster was just yucking it up, ended up having someone else from the party decking this dude out cold.

People suck, pranks aren’t always funny (especially serious ones like this!!!!) and when someone takes it too far, they need to learn that it’s NOT okay. NT f-ing A. And DONT let this dude live with you again, EVER.

omgh4x − I don't think you are an A Hole. I think you had a very justifiable, emotional, response to what he did. He is 17 and has no idea the fear you had as a parent in that moment. I'm sure him seeing you as distraught as you were will smarten him up.

[Reddit User] − NTA. Those types of “pranks” are sick and definitely not funny. I don’t blame you for sending him back to live with mom. Mom is on your case because she doesn’t want him back in her house. As for your husband, he needs to get on your side, like now. Ask him what he would’ve done if he were the one to see this prank?

Girl_Of_Iridescence − NTA- on April fools when I was 7 my dad wanted me to prank my mom and slide down the stairs like I did for fun but pretend like I fell. I told him I wouldn’t do it because it would be mean.. I was 7. Your brother is f**ked up if he thought that would have been funny.

Reddit’s hot takes back OP’s fury, slamming Jacob’s prank as cruel and thoughtless. Many see her reaction as a natural response to a parent’s worst fear, though some urge forgiveness given his age. The consensus? Pranks like this aren’t funny, and consequences are a tough but necessary lesson. But do these fiery opinions capture the full nuance, or are they just fueling the family fallout?

This staircase scare shows how a teen’s reckless prank can ignite a new parent’s deepest fears. OP’s decision to kick Jacob out stemmed from raw maternal instinct, though her family’s push for leniency raises questions about forgiveness versus accountability. A prank gone wrong doesn’t have to end family ties, but it demands clear boundaries. Have you ever faced a prank that crossed the line? How would you balance discipline and second chances in OP’s shoes? Share your thoughts below!
