Well of course your mother is not happy about her 16 year old having a baby. Why would she be? Who would?
You don't get to tell her she's being unreasonable. She's expected to house this new baby, pay for it, take care of it...she doesn't have to just be happy and ok with it.
If your sister thinks she is old enough to be a mother, what has she done to find a home for her child, and to support it?
This.
You say that your family say they will “support your sisters choice” but I’m not sure what that means.
Do you mean that the rest of the family ( whoever that is ) are willing to have your sister live with them, give up their jobs and care full time for her baby while she goes back to school / college , has a social life, goes out with her mates etc.
Or do you mean “ supportive of her choices “ in that they say the words “ yeah babe you go for it, your body your life, babies are cute “.
If you are being supportive of your sister then why can’t she continue to live at yours ? Your baby doesn’t need it’s own room - plenty babies and toddlers share with their parents. You have had fun being pregnant together, now you can have fun being mums together.
If you want to withdraw your support of your sister, then presumably you are not going to throw her out on the streets heavily pregnant. I assume you will help her find somewhere else to live, maybe with all these other supportive family members. Or help her apply for housing from the council, since you are making her homeless.
You can’t have it both ways . I am supportive but I don’t want to deal with her baby. My mother doesn’t want to deal with her baby but she’s a selfish bitch.
My sister is an adult who has the right to chose to have this baby and care for it. My sister is a helpless child who needs other people to care for her baby.
Which one is it?
You seem to want the glory of being “ supportive “ while expecting your “unsupportive “ mother to give up her home, job, money and life to care for a baby that isn’t hers any didn’t choose.
