After walking upstairs and seeing Tyler's cute little face looking over the crib railing, we decided it was time to move the crib to the lowest level. He can now get on his knees in the crib. He has not tried to stand up in his crib yet but I have seen him pull himself to a standing position several other times. I didn't want to take the chance of him falling out of the crib. Here is the cute little face that got to walk into.
