Choose a beautiful place with intriguing terrain (thanks, Julie, for the recommendation!)
If you come to a bridge, be sure to trip-trap over it both ways, again and again, before moving on.
Go slowly. Very slowly. Have no expectations in mind other than having fun.
Take a rest whenever you need one. Maybe a nap on a rock step.
Stop to admire the view (remember that the toddler's view is smaller and lower than your own).
Be prepared to give a boost when needed.
(We hiked some portion of the Emery Path in Acadia this morning. It was perfect for Lucy right now--almost all stairs!)
