Using his weakness against him

Cam is utterly obsessed with Thomas the tank engine or choo choo as he calls them.
Mummy used this to her advantage today after cam had finished nursery. She had to go to the doctors and to avoid the usually screaming sessions we have every time we visit she had a secret weapon. A new Thomas book. It worked like a charm. A bit of shameless bribery seems to be the way forward ;-)
