oooh, we just did a day out in London, with my 3yr old and 17 mth old; we took a ferry from Greenwich pier to the London eye; then walked down the south bank - slowly cos of all the entertainers/street jugglers etc; crossed the bridge and walked up to Covent Garden, again to watch entertainers in the piazza; Ferry back to Greenwich - saw the Cutty Sark before it burnt down
then had late afternoon/early evening picnic in the park, played footie and chase;
fabulous day! xx
