Physical manipulation was too much for both me and Lila. I took an easier approach by getting her comfortable on easy stairs first. Big, wide, solid steps like outdoors at public buildings – schools, libraries, offices, etc. I took Lila to the local college and started out with just a few steps then moved to buildings with more or steeper steps. That was enough for her to figure out how to make her legs go and be confident going up and down.
Good luck!
