Possibly a silly question, sorry (!), but I've never taken a baby on a train before. It's a short journey (20 mins) by myself with my 13 month old. Can I leave her in her buggy when I get on or will I have to collapse it and sit her on my knee? Just wondering logistically how I'm going to collapse a buggy whilst holding a baby in one arm 🤦🏼♀️ so would prefer to leave her in it for the journey. What's the rules/etiquette with this? Thank you!
