A mother ’s milk provides everything the pups need during their first four weeks of life. If you are caring for an orphan or the mother is out of the picture, consult with a veterinarian for guidance on the proper way to bottle-feed newborns, as it is easy to cause harm by doing it incorrectly. The babies will need to be fed a commercial canine milk replacer. Be sure to use one specifically formulated for puppies, as cow’s milk and other milk replacer can cause .
• Breastfeeding newborns don’t overeat. Between days 6-10 postpartum, mothers are capable of producing an average of 1200 g of milk per day. But their babies consume far less than this—-about 500-700 g/day (Casey et al., 1986; Saint et al., 1984).
During these growth spurts, it will feel like your newborn is feeding almost constantly (and like when she’s not feeding, she’s sleeping). This is 100% normal – feed your newborn as often as she needs it, as the extra nourishment is important during the growth spurt.
Similarly, the American Academy of Pediatrics advises parents to feed newborns "whenever they show signs of hunger," or approximately 8-12 times every 24-hours (Work Group on Breastfeeding 1997).
