I have exactly this problem- my DS is 15 mo. The only thing I do is to give him rice cakes (which works for about 20mins, then the grabbing and crying starts again). Also, I think it's getting a bit better as he gets older, and if I'm in a big Tesco or similar I often find a £1 toy near the start of the shop which sometimes fascinates him for a little while. It's a shame because he loves going to the supermarket with Dad/GPs but the lure of boob is too much sometimes when I take him!
Ds 14 months mostly feeds at home but as soon as i put him in a supermarket trolley he turns into some kind of boob grabbing demon. I am 5' 2 so my chest is right by his face and its just too much for the poor boy. He starts creating and grabbing my clothes, pulling my top down.
how can I get round the shop without flashing people?
