I have a 17 month old DS. He has been cruising around furniture from around 12 months and can walk holding one finger. He is not walking by himself yet but he does "walk" on his knees. Has anyone seen this before? I'm curious to know if it's common. I'm not worried yet as I know he is within the normal perimeters of walking age but I can't help but wonder. His two older brothers both walked independently within a week of their first birthday.
