Emma's communication skills are growing

For a couple of months now, Emma has told us that she's tired by picking up her blanket and "handing" it to us so that we will take her to her bed. This morning, she was standing up in her play yard with blankie in hand and paci in mouth. I asked her if she was ready to go "night night" and she actually NODDED her head up and down telling me YES, she was most definitely ready to go take her nap. And she must really have been tired because I haven't heard a peep from her in the 20 minutes she's been up there. I wonder what she does all night to make her so tired in the morning?
