... and I did the nursery pick up with the trailer today. I was driving her in this morning (we were late and it looked like rain) and she said "Can I ride in the trailer today?" So I picked her up later by bike
It's such a small thing but it's making such a difference - I've done 7miles by bike this week that I'd have otherwise done by car. So I'm fitter, dd has had more time in the fresh air, and I haven't been wasting fuel on short journeys. Drivers are generally excellent too, I'm getting a lot of courtesy and friendly waves even when the trailer is empty! Thanks again for all the sensible advice.
