My toddler hates me

I just gave birth to my second child a few days ago

From the second My toddler met her little brother she has been refusing to even look at me. I feel awful.

If I try to make her sit by me, she’ll come and sit for a second and then leave then she throws a huge tantrum and just doesn't want anything to do with me.

I know it's hard to bring home a newborn, and I know she hates that I have to divide my attention But does anyone have any tips on how to get through this and make it easier on her?

I have tried including her in everything, but she just really doesn't want to be around me or the baby.

I feel like I ruined her life and I am so sad because it isn’t the same relationship we used to have. She was my best friend and we had so much fun together now she doesn’t even want to be near me 😩 I’m so sad
