Any ideas about tis? DS1 never did it, was naturally quite cautious and stuck within a pretty close radius. DS2 is toally different- physically adventurous and very bold - but beyond a joke. He starts running when I put im down or let him out of the buggy and won't stop whatever I shout. I have tried walking in the other direction shouting 'bye' but once he has the bit between his teeth he doesn't care.. I have even hid out of sight for a bit to see what he does.. nothing - not really bothered. Otherwise we are well bonded and he is always happy to see me when I come home etc, running into my arms. Obviously I am bothered because it is dangerous and if he gets a headstart there is a real possibility he could reach a road. Trouble is, casing him seems fun for him. He is actually a little sod sometimes and laughs as he runs. Any suggestions?
