School pick-ups for two kids while I recover, Strasbourg

I'm Pauline, a parent in Strasbourg. I'm recovering from a broken ankle and have been told not to drive or carry anything heavy for about 3 weeks. My children are six and nine, and the school is 4 miles away. I'm looking for parents or neighbors who could take one or two pick-ups a week, or walk with them. I can do the cooking and homework in return once I'm back on my feet, and I'm glad to share fuel costs. The school knows and is flexible about who collects the children as long as I give your name in advance. If this is something you could do, please write to me through the offer button.
