Every single time DP makes a hot drink for himself he leaves it on the side with the handle hanging over the edge. Every time I ask him to move it to the back out of reach or I do it myself. Our toddler is very mobile and all it would take is for her to pull it with her hand and she'll be badly injured, not to mention scarred for life.
I don't think I'm being a nag or unreasonable to ask. I scan every situation for possible hazards as I think every parent would.
What do you think?
