One year old, and how time flies! Baby will have come along so much since being born; no longer such a demanding little bundle of skin and crying, but now a little person slowly growing their own personality. Many babies are walking by now, but if she's not then don't worry, this will come along soon. Her babbling may have settled somewhat if she's walking; now that she can move and explore she's less interested in talking and more interested in doing stuff.
On the flip side of this, when she does communicate with you it'll be more of a two-way street: her understanding of the names and functions of objects is growing. For example, if you ask her where the dog is she may point at him. Her interest in energetic, boisterous play will increase, and this will help strengthen her legs, hips, and arms. She will now really benefit from counting games, and you pointing out the names and colours of items, such as fruits and vegetables.
