Several weeks ago, on our walk we came across a digger, parked on the road.
When we went by it the first time, Hailey was very scared and almost didn't want to pass it. I think she only found it in her heart to keep walking because we were on her favourite street.
On the way back (can't avoid it as the road is a dead end), Hailey was much braver and wanted to smell it and check it out. I let her take as much time as she wanted to check it out so she would realize new things aren't always scary.
