Once my Bp starts to shed and I realise it's not complete, I put her in a warm bath, leave to soak for about 5 mins to loosen the skin and I get a snippet of a towel and finish it myself.
Gently rub the towel snippet over the shed edges (front to back motion) with a little pressure, and the shed will roll right off, some say they are tender and sensitive after a fresh shed, but my girl doesn't seem to care, she just climbs right onto my hand once I reach into her tank.
