He hasn't cried on a motorway, the only times he's been on one I've been sat next to him so we played, looked out of the window and he slept.
This is how we deal with long car journeys too. Doesn't half put some people's backs up when I tell them, you'd think I was making them do it the way they carry on. "You shouldn't pander to her like that!", "It's not fair on your DP to be up the front all by himself" (but apparently it's fair on my baby to be on her own in the back??), "It's good for them to learn they're not the most important thing in the world" (at one year old??).
Again, my choice. I could spend car journeys sitting in the back playing and chatting with my kid, while DP concentrates on the driving, or I could sit in the front, possibly have to listen to her cry without being able to do anything about it, do my neck in craning round to talk to her/try and sort her out if she gets upset/spills her drink on herself/drops her toy... for what exactly? To teach her a lesson? What lesson?
Any long trips I have to do with her by myself I use public transport. Again my choice, easier for me. And for short solo trips, I tend to whack on the Ipad with a bit of back-to-back Duggee and that sorts things out for 20 mins or so

And as for crying in the pram - slings are your friend! goes off to knit own muesli
