The climber is back

Early on Andrew worried me with his climbing ability, then it tapered off. Well, in the last week Andrew has mastered going up and down stairs safely, climbing onto our couches and just now, climbing onto our dining room chairs. I even tried to push the chair all the way under the table to make it difficult (or so I thought). He still climbed up and just stayed low under the table on the seat. Crazy! He seems to have a fairly good sense of balance and how to avoid falling, but he's not quite 15 months old. I can feel my gray hairs forming as I watch him run along our couch.
