I know it is normal for two year olds to fail to come when they are called - but mine is the worst I know.
E.g. at the park with friends, they call their dc, who are the same age, and mostly they come. My dd invariably looks at me, laughs, and heads off in the opposite direction.
She is hell bent on escaping from me wherever we are, I know I can use reins/buggy for safety's sake, but I would really love to teach her to come when she is called. Is luring her by shaking a bag of buttons the only answer? I fear that I will become a kind of pied piper, collecting lots of toddlers wherever I go...
