I'm another that never considered using a harness...until Moo started to walk. He is a runner & can very easily get away from us. Yesterday he ran off in the supermarket & was halfway across the shop before I got to the end of the aisle! I plan to use the harness as others have mentioned - holding his hand/him holding the pram strap with it around my wrist. I'm at the point where I don't go shopping alone as he screams & tries to get out of his pram, it's just too stressful. It doesn't bother me what other people might think because he is my child & I know what is best for us.
