Any suggestions on how to protect this brick so my toddler doesn't get hurt? She's about to walk and the last thing I want is an ER visit for stitches. We're renting this house so I can't glue or tape anything to the brick. I have some foam pipe insulation, but haven't found a good way to attach it. Home Depot sells some specialty made items, but it affixes with double-sided tape. (And, if we owned this home, you bet there would be an insert in that fireplace.)
