Our eldest son sure loves to climb! He climbs up on everything he can (monkey bars, trees, etc.), and is constantly asking me to help him get higher. Sometimes he says he is scared and asks me to help him down... but other times, he overcomes his fear and just keeps climbing!
I do my best not to helicopter over him when he climbs... it's getting easier as he gets older and more coordinated. We may take him to a climbing program later this summer... he's been climbing twice (for free at local street festivals) and loved it each time!
Is your LO a climber?
