We had sunday lunch in a pub and I was holding DS (9 months almost) as he was a bit bored. MIL sat opposite and suddenly I hear this noise so I look at what he is doing... he was rattling a set of keys dangerously close to his face and making marks in the table.. !!!! MIL was smiling and thought this was a great distraction. How anyone can think keys are suitable toys for a baby I don't know.
Also she bought him a Golliwog , which I have hidden at the bottom of his toy chest so it will never resurface again..
