Whatever works for you, we all have experienced this at s ok me point. To the harness, as l recently saw at the airport, it honestly looked weird, girl restrained on 2m leash and people do stare. Rather than this option l would practise with her on staying close, holding hand, basic safety if she would get lost bcs that is what she needs to learn and use on daily basis. Also, make an bracelet or write your phone # on her wrist!
