When my sister had my niece, i wasnt jealous but i was very sad. I remember crying because i just knew our bond would be forever changed and i wasnt ready for that. My sister was/still is my best friend and i just remember feeling so out the mix if that makes sense. I was 19, i helped my sister buy things and prepare for my niece knowing lowkey i was dreading her birth cos i was so convinced things would change !! The day she was born, I was nervous .. But as time went on i realized how motherhood shaped my sister and she was still my best friend but now i had a broke best friend too. My niece became the first daughter i didnt give birth to but she was my baby ❤️ I say this story because it’s maybe scary for her. She obviously loves your husband alot and loves there bond. I think she will have a change of heart once she realizes nothing will really change, and she will build her own bond with your baby girl in due time. Give it time,
Yes I don’t think is fair for her to feel like that because my me and my partner waited a very long time to have kids, we been together for 11 years and struggled with infertility. I remember when me and him first got together she told me, you can’t have a kid with him because he said he wouldn’t have kids till he set me for life 🥴 At the time i was young and wasn’t even interested in having kids. I think the reason why she feel this way is because she depends to much on him and feels like she wouldn’t be able to or he would be more hesitant to put up with her And her behavior. She is currently working for him is not like she would be affected by time they spend together because she sees him everyday.
Tell her she needs to talk her feelings through with a therapist x
My aunt was 16 when my mum and dad had my oldest brother. She made a massive deal out of it. Saying my mum was stealing her brother away (he left to join the navy 4 years prior and was never close to her!) And she was super mad when they didn't make her god mother (at 16!) Sounds just like a jealous sister thing, but it's good that she's spoken about it and you can let her be as involved as you guys are comfortable with. Just let your partner know that she's worried about losing her big brother and maybe he can make a point on having some one on one time with her occasionally, maybe a cinema date or something. I still like to play the odd board game with my little brother because that's what we've always done, and it has been hard to have that sibling time since my son was born.
Accountability is great but it honestly sounds like she needs therapy
Try to incorporate the sisters into the little ones life it will help with the transition. You can do movie nights with them or a bbq it will help them not feel displaced if they get time to be with the brother and baby together
Ew.
She is not a kid. Sounds like she needs to get over herself because the world does not revolve around her 🤷♀️ being jealous of a baby is ridiculous. You can have a relationship with an older sibling when they have kids. I have great relationships with my 4 younger siblings. They love my son to death!
