He's gone from holding nervously onto the handlebars on my wifes bike, to being quite comfortable just sitting and checking everything out as we ride along on my bike (mountain bike with handle bars that are forward so can't be reached). He blethers away like mad when we are going along, and funnily enough he always seems quite shattered when we have been on a long trip (little brain taking things in at 10 to the dozen). It enables me to get things done reasonably quick if needs be, rather than public transport, buggys, baby bags, etc.
