She is a tall kid? My girl, now, 21 mths, is just 11 kg, 80cm.
When she was 13 mths, she was a little scared but at 14 month, she discovered the freedom.
By 16 mths, she was running around. Of course, a few falls which I thought is 'good'. She learn how to fall ie. use hands to support so that her head will not be hurt.. I let her fall and will not deliberately go to catch her. Of course, with supervision..
My girl can speak well at 13mth, called Papa, Mummy...
