i get v scared/anxious of trains and the underground. This saturday we are going into london to the zoo. dh saying easier to go by train but i dont want to (my sake really) when you are down by the underground its all hot and crowded and you get banged and no room etc. I havent been to the city for a few years due to these things. Please tell me whats is going to be like with a nearly 3yr old and a 5 month old?!
