She might just be at that age where she understand that you and her are two different people with different needs and wishes. Is she throwing tantrums as well? Scotty never hugged me until hubby and I completely let go of the idea of hugging. We just said that is the way it is and we can't do anything about it. Since then he comes to us and hugs, but only when there are no toys or light swtches in sight and he is quitely sitting on my lap before bed. I love it
Wind down is the only time I ever get hugs now... Just don't force her, don't make her thing you catch and and will hold her on your lap, she needs to know that what she wants to to with her body is respected. It might take a while but hey - everything is a phase at that age
