Hi there, I'm travelling alone with my crawling, standing but not walking 10 month old on a train to London next week (Intercity type train - journey 2 1/2 hours). Anyone got any tips on keeping him amused? Is it worth buying a booster seat for him to sit on seeing as I won't be able to keep the buggy up on the train? I'm travelling at lunchtimes both ways and hoping to bribe him with food!
