Oh Gigi, you scamp! I think this might be expected, as she naturally gets more curious and agile as she grows! I don't see any problem with her staying in the playpen with her toys and a blankie without the crate, provided she can't climb over or knock over the pen! Was the crate door left open inside the pen before, where she could just go in and out as she pleased? If so, it sounds like she'd be fine in the pen without the crate, unless you think she'd be stressed without a den like refuge for privacy
