I am going to take the credit for this.
Our grandson now does a "High Five" gesture when he sees me as a result of my persistence with it. Over a day or two he has even added a touch of his own - a wiggle of his thumb.
It is very endearing and just adds to his charm.
It is a pity he is not yet sleeping better at night!
