Chad's milestones

Chad can go down the stairs. I haven't really given him a chance. We have a gate at the top of our stairs so the other day the gate was down and he was down by the door and so I decided to watch how he does it. He walks right up to the top stop and steps forward to the next stair and then he turns around to go down backwards. It scares me every time. I have never seen a toddler do that before. But he has it mastered now.
