I'm sure DD1 was manipulating us by not walking - seriously, she was living a duplicitous life at 15 months! One where she would walk at Childcare and the other where she would only crawl at home!! Everyone had seen her walk but us She is the sort of kid who won't do something unless she is is pretty confident she can actually do it - quite cautious and risk averse.

We eventually tricked her into walking at home by having us sit opposite each other, with our leg straddled apart and got her walking from one to the other gradually letting her go and walking by herself. Once she had done it for us then she continued to do it. It was pretty funny though!
