It took 2 1/2 years and a painful molt, but recently Ham has let me rub her head and neck with my bare fingers! As most know on here she has never liked hands. Now however she actually expects a little head rub every night and the great thing is she lays her head against my chest and closes her eyes while I do it, and even vibrates. Awwww!
During this long time I never forced contact on her but let her set the pace. So for any newbie who thinks things should be done and dusted in 4 days, develop a longer timeframe and both of you will be happier.
