Mil has blinds with strings all through her house. Nephew is 2 and there all the time under MIL's care.
I saw him playing with the cord and as MIL was elsewhere, I stopped him with distraction.
She has hook things halfway up the window wall...the edge of the wall inside whatever that area is called...and the cords are through the hook somehow. SHe says it's a safety mechanism but the way I'm looking at it, Dnephew could still get his head in it if he climbed on something.
AIBU to say something twice? I expressed my concern in a careful way but she brushed it off and said the hooks meant they were safe.
She's not always in the same room with nephew when she's babysitting. He is a climber and he is curious and likes doors generally
