Imagine you are a mother in a rural area of the Kingdom of Tonga, an island nation in the South Pacific. Eleven months ago you gave birth to your third child, a beautiful little boy.
Everything seems fine until you begin to notice that he still doesn’t hold his head up on his own. Whenever you try to sit him up, he slouches to the side. Your other children had already begun crawling by this time, but he still lays on his stomach or back.
