My daugher does not like her brother.

While I'm not positive, nor an authority, it sounds like it just might be rooted in jealousy. That's a lot of years between the two kids, and for all of those years before he was born, she was the center of attention. Then when a baby comes along and takes up SO much of Mom's time, it's easy to see where a kid might feel displaced. I think forcing her to become closer might actually be hurting more than helping in some ways. At 12, they're just a mush of conflicting emotions anyways lol (or at least my girls were at that age.) Maybe some pure one on one time with Mom more might help, where you just take her out shopping, or something she'd like to do, without her little brother tagging along. You know, keeping the total focus on her for during the outing. I can relate though, I had two kids, and now have grandchildren. Not being judgemental, it's hard to parent a 2 year old!! And it's really tough when girls are in those tween years too...not a teen and still not a little kid. Anyways, I wish you good luck whatever you do. Here's a huge Mom to Mom hug!
