Hi, I want to know what position can replace child position and give me exacly the same benefits? Because I can't do it properly and I don't feel it when I'm doing it. The top of my feet can't even be flat on the floor it's giving me pain.
Use pillow to support your legs and do it.
But eventually, you need to fix that. If you find difficulty in doing any simple posture then it is an indication that your body has that limitations or deformity or muscle imbalance.
The beauty of yoga is that it predicts your future illness by indicating limitations today.
