Help for 16 month old

[ettelloc]

My 16 month old son is very lively and energetic like any other toddler. Generally he is well behaved but just lately he has started screaming and continues to do things that we have told him no, for example not to touch the oven as its hot. He knows its wrong because he looks straight at you as he's doing it. The screaming thing I think is just a phase and has probably picked it up from nursery, seems to be a frustration thing but I cant get him to listen when I tell him no. He also likes to run away from us when we are out shopping etc. He gets fed up when sitting in the trolly so we let him walk and tell him to stay with us, he does for a while but then runs off. Can any give any advise?

When my daughter was small I would put her in the trolley and talk to her as we went round - she didn't need to be distracted because she was happy with me chatting with her.
