If you've got a climber you're just going to have to let him get on with it. Take a few precautions like putting some cushions down around regular climb-zones, lowering the cot-side once he can get to the top of it, and redirecting him away from the things you don't want him climbing on to things it is OK for him to climb on - and get him into Kindergym just as soon as you can.

ENJOY having a little monkey, neither of mine have been climbers but I have a good friend who had three climbers - they are all fantastically physically-aware and well coordinated children now - all fantastic life skills!
