Daughter not bonding with baby brother

Gabi

My daughter turned 8 in October & my son will be 2 in February. I know the GAP is HUGE! The issue is, my daughter just wants NOTHING to do with my son. She doesn’t want to play with him, be around him, sit with him, she doesn’t hug him back when he hugs her, she doesn’t share her food/snacks, and the list goes on. It’s almost like he’s an inconvenience to her. It breaks my heart that she’s so cold with him. Before it’s mentioned, we have made sure both get equal love and attention from not just dad and I but EVERYONE. Grandparents, uncles, aunts… no one is more spoiled than the other. Regardless she’s our only daughter and he’s our only son. I’ve tried getting them to do activities together but she gets upset and goes to her room . For example if I lay things out to color, she will get mad that he reaches for colors she has or if he wants to join and color on her paper. You can feel and see the love my son has for his sister. And it’s just heartbreaking to see how she doesn’t reciprocate the same. I know I can’t make her love him, or show him love. But, I’m wondering is this a stage. I mean we’re going on two years of her not wanting anything to do with him. I want to share videos and pictures so you all can see but I rather keep my little ones private. But trust me y’all would be so overwhelmed seeing my sons reaction to getting rejected by her everyday 😕😢😣…
