The little man now enjoys standing up to play instead of sitting on the floor. He keeps getting more and more independent!! I stayed in the room and watched him when I put him down for his nap Monday night and I watched him make his way over to the railing of the crib and pull himself up to an almost standing position, it was more to his knees, but regardless I made RJ change the position in the crib. Now if he decides to stand all the way up there is no chance he will fall out!
