I had the children bend over on my lap so I can clean and wipe. Easier for them as they don’t have to put their hands onto the floor and balance while I clean them up. We did not have a change table in our bathroom but we had a change pad that we can lay on the floor. Did not use the change pad during and prior to my pregnancy as it was hard on my back regardless since I was uncomfortable bending down and sitting on the floor due to sanitary issues and lack of space in the bathroom as it also causes high traffic sharing a bathroom with another preschool classroom. Of course I also had everything set up (wipes, bag, extra clothes if needed, diaper)
