To let my niece stay when she refuses to see her mum?

My sister has 2 children, my niece is 20 and my nephew is only 10 months, so a huge age gap. They have different fathers.

My niece is at university and since my sister had the baby, my niece has refused to spend holidays at home, preferring to stay in her uni city with friends. My sister isn’t happy with this but has had to accept it. My niece has told her that she doesn’t want anything to do with her or the baby. She thinks her mum is mad for having another child. My sister and partner have been together for 5 years and he moved in when my niece was 17. My niece got on ok with him but didn’t like him living with them.

My niece planned to stay in her uni city for summer but asked if she can spend the summer with us a couple of weeks ago. I said she could but that she should tell her mum. She did and my sister said we shouldn’t let her stay with us and we will make things worse.

My niece came to us last week and my sister is angry. I said that I am being neutral but that I will speak to my niece about how she’s feeling and try to help them sort out their relationship. My sister thinks I should tell her that she can’t stay with us but I’ve said she will always be welcome here. My niece is such a nice person but she is adamant she wants nothing to do with her mum, her partner or the new baby.

I feel really in the middle but my niece is still really young and I wasn’t going to turn her away. I’ve tried to put myself in my sisters shoes but it’s difficult as I can’t imagine having another child now and how my children would feel about that.

I’m going to let her stay but going forward what would you do? I’ve suggested to my niece that her mum comes for a coffee or to meet for a walk with or without the baby to try to sort things out but my niece isn’t interested. She just seems to be getting on with her life and seems happy without her mum in it. She helps around the house, gets on well with my children who are also home from uni, goes out with friends and is working. It’s like she has just wiped her mum out of her life, They had a good relationship until her mums partner moved in. She says she feels her mum put him first and although her partner is ok, she didn’t like living with another person.

I can see why your niece cut her mum off. Your sister is manipulative and trying to isolate the rest of the family from her own daughter because daughter isn't dancing to her tune.

I feel for the poor girl. Yes she is an adult but she has been well and truly replaced.

If your niece didn't stay with you, is there a possibility she would try to patch things up with her mum, if only so she had somewhere to stay?

Your niece sounds incredibly spoiled and I feel for your sister, I wouldn't stop her staying though as at least it keeps communication open.

She isn’t at all. When my sister met her partner, she introduced him very quickly to my niece. He was staying over most nights within weeks so almost living there and then properly moved in after about 15 months. My niece would ask to do things with my sister and she always invited her partner along. My niece feels like she put him first and that as soon as she met him, she no longer spent time with just her. I spoke to my sister about it at the time but she told me my niece was fine and it wasn’t my business. I couldn’t say much because what I knew was through my daughter telling me what my niece was telling her. My niece started having more sleepovers with us but my sister said that was just what teens did with their cousins and not to do with her being upset with the new partner living with them.

Tbh OP I feel for your sister in this...although your niece is still young, she is an adult and is being very immature to cut her mum out of her life like this, especially since they had a good relationship before. Her mum hasn't done anything wrong.

I don't blame you for taking her in but I can see why your sister is annoyed. It's good that you're encouraging her to talk to her mum, and hopefully with time she will mature a little and see what she's missing out on.

In the meantime I'd continue the encouragement, maybe your sister could drop round and tey to talk to her in person? Since she won't actually agree to meet.
