I'm going travelling on my own with toddler (18 months). I'll need to catch 2 planes and 1 train. How on earth do I push a pram and carry luggage? I'm thinking I might need one of those giant backpacker rucksacks? Or maybe a really good wheely suitcase that I can push with 1 hand? What have other people done? Any other tips on the practicalities of travel with a toddler gratefully welcomed!!
