Loss of my last safe haven

There has been a new development in the toddler’s world. She has had this little plastic step for a while but has recently discovered she can pick it up and move it around the house, step up on it and get to more places. I also have found it handy as it normally sits next to kitchen bench or kitchen table… But that’s another story.
So yesterday she picks it up (assume it was in the kitchen), brings it to mum’s bedroom and WHAM… Just like that my last safe haven on mum’s bed is gone… She can climb onto the bed.
Short of climbing up a tree (refer to earlier post for that attempt… And it doesn’t look all that comfortable) I am running out of places to escape.
