Deer Mothers and Nursing Behavior
Female deer, known as does, nurse their fawns, providing essential nourishment during their early, vulnerable stages of life. This natural process is fundamental to a fawn’s development and survival in the wild. Maternal care ensures the young receive the sustenance and protection needed to thrive.
Immediately after birth, a doe initiates maternal care. Newborn fawns are born with a spotted coat and very little scent, which helps them blend into their surroundings. Does lick their fawns clean to minimize scent that might attract predators and often consume the afterbirth. Fawns are “hiders,” spending over 95 percent of their time hidden and motionless during their first week.
The mother deer keeps a distance from her hidden fawn but remains nearby. She returns periodically, four to six times a day, to nurse. Upon approach, the doe may emit a low “maternal grunt” to call the fawn. During nursing, the fawn bumps the udder to stimulate milk flow. The doe also licks the fawn’s anal and genital areas to stimulate urination and defecation, consuming waste to maintain a low scent profile. After nursing, the mother nudges the fawn back down before she departs.
Duration of Fawn Nursing
The nursing period for deer fawns involves a transition to solid vegetation. Fawns rely exclusively on their mother’s milk for the first two weeks, then begin to nibble on tender vegetation. This helps them learn about edible plants and initiates the development of their four-chambered stomach, the rumen.
Fawns can be fully weaned as early as 10 weeks. However, does often nurse for 12 to 16 weeks, or even up to five months. This prolonged nursing provides additional nutritional support and helps fawns develop foraging skills. Female fawns often remain with their mothers for up to a year, while male fawns typically disperse earlier.

The Vital Role of Mother’s Milk
Mother’s milk supports a fawn’s development and survival, providing a dense nutritional profile for rapid growth. Deer milk is concentrated, containing 25% milk solids, with half composed of milk fat. This high fat and protein content (over twice that of cow’s milk) supplies energy for a fawn to double its birth weight within two weeks and triple it within a month.
Deer milk is abundant in vitamins and minerals, including calcium, phosphorus, magnesium, and zinc. It also provides omega fatty acids, phospholipids, and gangliosides, which support brain development and immune function. The initial milk, colostrum, is rich in antibodies that transfer passive immunity from the doe to the fawn, offering protection against diseases. Deer milk contains lactoferrin, which has antibacterial and antiviral properties and promotes bone health. This comprehensive nutritional support ensures the fawn’s robust development and resilience in its early life.
