Has Mummy got some new panniers for her bike? There seems to be something protruding from the aft side of her bike?

Not at all! It is Lucy attached using a
Trail-Gator. In years to come this may be how Mummy takes Lucy to school. They might need a bit of practice first though. You can't use it with stabilisers (as this would prevent you cornering) and neither Mummy or Lucy are
famed for their sense of balance.
