Do you personally send and/or pick-up your kids at school?

I have 2 kids and now they both go to the same school though a little different timing. We have always made them use the school bus, and I put them in the bus and pick them up from it too. It was only once when my elder one was small that she was scared about something and refused to go in the bus. During that time, I personally took her to school each day and picked her up from there, for about 4 5 months.
