#AskTheExpert my baby's birth weight was 3.21kgs. today she is 18days old and her weight is 2.89kgs. whats the possible reason of weight loss and whats the ideal weight gain

A. hi dear A healthy newborn is expected to lose 7% to 10% of the birth weight, but should regain that weight within the first 2 weeks or so after birth. During their first month, most newborns gain weight at a rate of about 1 ounce (30 grams) per day.
