milk, breasts
乳 centers on the nourishing liquid produced by mammals: milk, and by extension the breasts that produce it.
乳 combines 孚 (a hand over a child, suggesting nurturing) with 乚 (a curved line possibly representing a breast or milk flow), together expressing milk and breastfeeding.
The left side 孚 shows a hand reaching down to a child, and the right side 乚 curves like a breast or a stream of milk. Together they picture a mother nursing her baby: 乳 is milk.
For ニュウ, imagine a new mother producing milk: new -> ニュウ, and the baby drinks from the breast.
