Travelling for three hours on a train on my own to see my parents who are in the country for a short time. DD is 20 months and usually well behaved. I've flown on my own with her before but never on the train (DP has always been with me). I'm trying to treat it as an adventure but am also panicking that it'll be hell. Suppose I'm just asking for any advice or experiences? Also I'm travelling with Thames link and then greater anglia and just wondering whether I'll need to fold the pushchair when getting on and off the train? TIA
