Do you like standing around in the cold for up to 10 minutes at a time, taking 3-times longer to walk anywhere than you could do it yourself, or listening to your child whinge and cry all the way home? A journey which will also involve your child stropping on pavement, stopping in playground until he's exhausted or dashing down any interesting alleys along the way? I guess I don't prefer those options.
Lis103: I used to loan my double buggy to ChildM. for the day and since we had to get it home again, anyway, DS almost always rode. I have a 2yo so bring a pushchair for her, anyway, whenever we go out. She walks very well, until she's tired or cold, and DS just rides in the pushchair until DD demands it. Then he tries to coax her to sit on his lap but she usually doesn't go for it. Then DS gets out, but walks very very very slowly. Childminder used to comment how slow he is, too! 3 weeks ago we couldn't find anywhere in our temporary rented house to store the double buggy so gave it to a friend to store.
Thus, DS is now walking more than it used to, but a walk that should take 15-20 minutes tends to take 70-80 minutes, with stop-and-stares, "What's that, Mummy?", strops on pavement and "I'm hungry!" pleas. So I have to plan ahead for the long travel times, bring money, snacks, water, etc.
