Planning a long-ish train journey on my own with a 6.5mo, any tips? Not sure what to carry him in. He can't sit up by himself yet. Do I take a pushchair for him to sit in on the journey and can you get one on a train - it's a big heavy travel system type so not the sort you can easily fold away, and he will get sick of sitting on my knee anyway and will need somewhere to sleep. Or carry him in a sling (could get tiring). Am being met at the other end by friends who have a car seat so that's not an issue. Any advice??
