Newborns are tiny, fragile, helpless things. Even leaving them lying in the wrong position, unable to reposition themselves, can be disastrous. Watching one, especially when you're inexperienced and not even an adult yourself, is understandably nerve-wracking.

The brother's demand that his younger sister watch his newborn just because she offered to babysit at some point in the future is reminiscent of any other time you make an offer to do a favor for someone and they take the bounds of that favor way too far. Like offering to look after your friend's plants when they're away, and suddenly you're pet sitting and deep cleaning their house too. That moment of generosity was sorely regretted the entire time because the person just took it way too far. Surely she meant that she would watch her nephew at some point in the future, you know, when he was a toddler or something.

Further, the obligation of parenting is just something you sign up for when you become a parent. The inconvenience of having to watch your child and miss things because of that is just a part of the deal, and you can't just take that out on your teenage sister because she's uncomfortable with your unreasonable request.

    "AITA for not babysitting my nephew"

    im 17 and my older brother (27) and his wife just recently had their first baby. I was obviously so excited and when they asked if i would babysit in the future i said of course. However i was not expecting it to be this soon. My nephew just turned 2 months when they asked if i could baby sit for the whole day while they go to a wedding. Ive baby sat my cousins before, the youngest being 3years old. I've never been around let alone had a baby as young as my nephew in my care before.

    I told them im not comfortable as he's still really young so i wouldn't be fit to take care of him by myself. They told me to relax and ill be fine. my brothers wife sent me youtube tutorials on how to change the diaper as well as paragraphs on how to feed him, the positions to lay him down in and how to make sure he's sleeping safely. This stressed me out even more because its a lot more responsibility and my biggest fear is making a mistake and god forbid something happening to him in my care

    When they came over again i told them i really couldn't. I'm quite intimidated and scared. I even asked my mum to come with me while i baby sat as that would make me more comfortable but she's a full time nurse and wouldn't be able to that day. My brother was visibly annoyed and started ranting to my family about how he now has to miss one of his best friends weddings. He said "well she was supposed to babysit but now it's another thing i have to deal with".

    I told them im sorry and he replied with "don't worry you won't ever be asked again". This made me sad because i do love kids and would love to babysit and bond with my nephew when he's older. Maybe im being dramatic and it wouldn't be so bad but idk. I feel like maybe im an a h_le for ruining their plans now.

    No_Glove_1575 NTA. You are not being dramatic, your bro and his wife are. He has to miss a wedding because of his 2 month old child? Thats called being a parent, and it's what he signed up for. And don't worry, he will DEFINITELY ask you to babysit in the future. And when he does, have pricing information ready for his entitled

    Midtow... NTA Your brother should have thought about the freedom he was giving up long before he and his wife decided to have children. EDIT: Although you are hurt by his actions, you should be relieved that you won't have to babysit for your entitled brother and sil. Anyone who thinks it's fine for you babysit a 2 month old with the only guidance you tube videos is either ignorant or neglectful or both.

    Administrative Sun364 ? They want you to baby sit a 2 month old? Are you even able to drive to the hospital if something happens? This is just insane. Nta and keep saying no. If anything goes wrong you will be the one to blame. It a lot of work with 2 month old. What if he start choking on milk?

    foreversenn NTA. Do not believe for a second that you are ruining their plans. They have adult family members they could go to. They could also hire someone.

    HoldFast02 NTA. You're supposed to babysit a two month old? For an entire day? By yourself? Your brother and SIL are tripping; this is a really bad idea. If your brother absolutely wants to go to the wedding, then the mom can stay home (or in a hotel room near the venue) and take care of the kid. Maybe you can come by for an hour or two on a supervised "trial run". But don't let them talk you into handling an entire day on your own.
