AITA for kicking my SiL out after she threw away most of my single use baby products and even formula?

A Redditor shared her frustration after her sister-in-law, a “crunchy parent” to an 8-month-old, threw away her formula and disposable baby products,

replacing them with reusable items that align with her own parenting style. This incident has led to a family rift and raised questions about boundaries. Read the full story below for more details.

‘ AITA for kicking my SiL out after she threw away most of my single use baby products and even formula?’

I’m 19f, I have a 3 week old baby girl. I do still live with my parents, but since I pay rent equally, they say I can have just as much of a say in who comes and goes from the house as they do. I’ve never actually taken advantage of this rule until recently enough. I have a brother, who’s 26 and his wife is 24.

They’re “crunchy parents” to a 8 month old. Basically what that is is f**king stupid, they use reusable wipes/nappies, think formula is the epitome of evil, babywearing, the list just goes on. I’m the complete opposite, pacifiers, supplementing with formula due to low supply, disposable wipes and nappies.

They are completely against the products I use and often give me things like SiLs breastmilk in bags, disposable nappies their LO has grown out of, etc. I’ve used some but it’s not really my cup of tea.

On Monday night, my bother and SiL were minding my baby for me since it was my birthday and my babys father (not together, very close friends and co parents) took me to get some dinner in one of my favourite fast food places. It was great and really relaxing.

When I got home that evening, my SiL said that she did some cleaning and “threw out anything I don’t need”. This immediately gave me red flags but they were in a hurry to get out the door and left almost immediately.

When I went into the nursery, every disposable nappy and wipe pack was gone and replaced with some reusable cloth ones. Same with my formula, there was 8 tubs and all of it was gone, I’m not able to replace them at the moment and soley breastfeeding isn’t sustainable for us.

I was extremely angry and I just turned my phone off to avoid being mean to my SiL. She and my brother came over yesterday to collect something they forgot and that was when I confronted her. I told her she has to replace everything she dumped.

When she said she can’t afford to, I said fine, just get out and don’t come back until I’ve been reimbursed or everything is replaced with the original items.

My brother thinks I’m being a massive a**hole and he’s on his wifes side. Our parents think im being completely reasonable here but they think telling her essentially not to come back is taking it too far. AITA?

Here’s what the community had to contribute:

onablanketwithmybaby −  NTA. Throwing away unused disposable diapers is even worse than using them and throwing them away. They are still going to the same place but have now doubled.

Formula is expensive and you say you’re supplementing… your baby is still getting breastmilk but needs a little more. That’s why formula was created. Your SIL was waaaaay out of line.

Even if she doesn’t agree with your parenting style, she has no right to sabotage it. It’s the baby that will suffer. She needs to replace it all or give you the money to replace it.

EggandSpoon42 −  So she saved the environment by (checks notes) throwing away all of your supplies. Makes sense. NTA and your SIL has a s**ew loose.

alimeluvr −  NTA sounds like theft to me. File a police report. She will replace.

Puzzled-Barnacle2771 −  NTA- that is easily over $300 worth of stuff! Also, women like her need to stop shaming other mothers. Breastfeeding is not the best option for everyone.

Left_Nectarine_2261 −  NTA. She can’t afford to replace the items, but fully expected you to do it? I would like to know the mental gymnastics she went through for that to make sense. I’m not sure she should be allowed back even after reimbursement.

Babsgarcia −  NTA – if your bro doesn’t understand ask him; **”how would you have felt, while you live on a budget — if I had been at your place and thrown out your stuff because I don’t ‘agree’ with it?

Bottom line is different parenting styles aren’t wrong – just that – different. If we both don’t learn to respect each other’s choices, this will be the first of many problems.

Is that how you want these cousins to grow up, with their parents fighting?** If he becomes reasonable, or they truly apologize, then maybe lift the ‘don’t come back’ and let them replace as able (with a deadline or it all comes back up)

MissMurderpants −  NTA. Yeah, I’d be mega pissed. That stuff is expensive. So instead of letting you use it.. she threw away good products? Does she not see the irony?

CyberAceKina −  NTA. Babies are EXPENSIVE. She trashed a lot of stuff that you can’t get back that your baby needs.

Korlat_Eleint −  NTA. They STOLE your items. And it was stupid as well of them as they just wasted all this stuff throwing it all into landfill instead of using it.

Spyral333 −  NTA. They have no right to throw away your possessions. It’s honestly like they robbed you and I feel you could contact the police about this. Baby items are extremely expensive and especially for a single mother.

Yes they’re parents but they’re not your child’s parents and have no say in the products you use. If they thought something could be legitimately harmful that’s different but obviously not the case here.

Do you think the Redditor was justified in standing her ground, or could there have been a different way to handle the conflict? How would you respond if someone overstepped like this? Share your thoughts below!
