Help with the school run after my surgery (Berlin)

I'm Marie, a parent in Berlin. I'm recovering from a broken ankle and have been told not to drive or carry anything heavy for about 6 weeks. My children are five and eight, and the school is 3 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. Thank you for reading, and for even thinking about it.
