Being a little spiderman is the sign of a very active child! You are going to have your hands FULL! I have a 14 month old who was/is the same way, climbing is his passion! Most kids I know cry when they fall down, say off a ladder, and then don't do it again. Mine cries for a second, gets up, and climbs the ladder again! We put my son in a big boy bed at 6 months because of the climbing! He has done fantastic in it! We decided it was better than to worry about him falling from the top of the crib bars! We started just with naps and taught him to get off the bed right away. Now, when he wakes up, he slides out of the bed and goes over to the baby gate we have in the doorway and will call out for us. As for the not sleeping thing, that will come and go for the first 2 years I am told. About every 3 months, when they are learning a new skill like climbing, crawling, etc, they will be so excited to practice, sleep will be disturbed. Enjoy your little spiderman and let him explore and develop those gross motor skills, just watch and be there to catch him if you need to!
