My DD 15 months is now a pretty good walker/runner. My question is, do you think it's necessary to hold hands when you're walking down the street? We live in London and so obviously there's dangers but I always walk close enough to her that I can grab her if she starts veering. Friends are really strict about making thier little ones hold hands if walking down a street - I'm not sure I can be arsed with it, feels a bit like training a dog to heel. What do other people advise? x
