I (17F) don’t want this to take up too much of anyone’s time so let me explain quickly.

My grandparents bought me this kit that lets you make stuffies/stuffed animals/plushies or whatever you call them. I made loads for myself at the time and for both my younger siblings when my mom was pregnant. Both my younger siblings died at birth or before it so they were put in a protective casing and they’re now on my mom and siblings grave.

My mom died a little over a year ago from cancer. She was sick for a year before. A day after my mom died my brother (20M) and I found out that dad had been with another woman when mom died and that he’d had a 3 year affair with this woman.

The first two or three weeks after mom died were rough for all those reasons and I went to live with another family member because I couldn’t look at my dad. He tried to stop me and has attempted to keep in touch but I went as no contact as I could while still being under 18. My brother is in full no contact with dad.

Dad married his affair partner and now they’re expecting a baby. He reached out to my family member and said he was hoping I’d make the baby stuffy like I did for my siblings. He said this baby is my sibling too even if I don’t want that to be true and that it would be so kind to let the baby feel loved by me. I’m not making it and my dad has realized that since it’s been several weeks now. So he reached out again and said if I can make them for other babies born close to me I should do it for this baby too and reminded my family member that again this baby will be my new sibling. My family member told dad it’s my decision and my answer is clear. My dad started a fight with the family member and said I needed to find a way to love and care for the baby because they don’t deserve both older living siblings refusing to know them.

But I don’t want to know the baby or make them stuffy. I don’t love this baby. I don’t care about them either. There won’t ever be a time where I’ll want any kind of relationship, even a distantly friendly one. That’s just not in the future. But there’s still a chance that not making the stuffy makes me an AH. So AITA?
