Do you children have an obsession with something strange?

My 13 month old DD has developed an obsession with towels...she carries one around with her all the time, cuddles it and lays on it, its cute....she is also the next Amalda Marcos she loves shoes hers, mine, her dads, visitors she tries to put them on her feet or my feet or she chews on them or tries to figure out how to undo and do them up.....AND clips like on high chairs and bouncers and such she will sit for up to 30 mins and try to do it up and if she gets it done up she laughs her head of them crack until you undo it so she can do it again :) Was just wondering what other weird obsessions other kids have :)
