We always knew Elijah liked experimenting with different textures: how they felt and especially how they sounded when hit or scraped across other textures. Lately, Elijah's favourite texture seems to be my hair.
He will happily sit next to me or on my lap and run his fingers through my hair. The look of sheer delight on his face as he does it is a sight to behold. He is very gentle, unlike when he is dealing with blocks, pegs, lids and other paraphernalia. I think he understands that it's part of me and that it deserves his respect. It certainly has him in awe.
