My granddaughter's hugs are a problem. Do you have any ideas?

This sounds interesting. I'm 12 my self (a girl) and I love to push peoples buttons trust me. But maybe something you could try is to hug on her extremely tight and maybe annoy or embarrass (in a family loving way) her. Or something that makes me feel bad is when some one I rly like (like my older cousin or aunt or mom) has a conversation with me and tells me to stop or when my mom sez it in front of everyone it makes me wNna stop
