Question: My baby is 2 days old and has lost weight. Is this normal?
Answer: Most babies lose weight until mom’s milk comes in on day 3. If your baby is breastfeeding well on day 1 and 2, the weight loss probably won’t exceed about 7% of baby’s birth weight. Weight loss greater than 7% may indicate that baby isn’t breastfeeding effectively yet.
A Lactation Consultant can assess the situation, determine if there is a concern, and assist, as needed. Once your milk is in, your baby should not lose any additional weight, and should begin to gain about 1 ounce per day or 5 ounces per week during the next 3-4 months.
