Although giraffe are usually physically and socially aloof it is nevertheless common for mothers with small calves to associate and a tendency for calves to cluster together in crèches in the care of a single adult female.
I have drawn this Botswana scene of a female giraffe of the southern African race suckling her infant beside a camel-thorn tree.  The other similar aged calf is in the care of this adult while its mother is away feeding within sight.
While the calf suckles, momentarily oblivious of her surrounds, the mother and companion calf focus their attention intently on something threatening or otherwise in the foreground.
