I just started treating a baby who is 12 months old s/p liver transplant and other significant medical history, at assessment in prone he could not lift his head off the floor or prop without max facilitation. I trialed my Wunzi on him, placed him on the floor and immediately he had prone prop on forearms with head extension in midline looking at toys. It was incredible. If I had not seen it with my own eyes I don’t think I would have believed it… he was able to sustain for several seconds on multiple consecutive trials. So grateful for all that you have contributed!
