ds1 has never done that running away thing that toddlers seem to love so much. He's the opposite - you go to a soft play area and have to coax him to go off and play, but he is usually back by my side within minutes.
I commented to my mum that I won't know what's hit me if ds2 turns out to run off at every opportunity, and she said "oh, all three of you were ball and chain toddlers, I never had a runner." She then went on to say that she thinks it runs in families.
So what do you have? runners or ball and chains, and has anyone had a mixture?
