I have a lively 18m old son and would love to be able to walk to the shops with him now that he is comfortably walking. Any tips on how to help him learn to walk safely without lurching out infront of traffic? The other thing is that he only wants to walk where he wants to go which is not always where I want to go. Have tried reins which are semi successful. He hates the buggy now as he wants to be out! Does anyone have any helpful hints????
