Question: how much weight should a breastfed newborn gain per week?
Answer: † It is acceptable for some babies to gain 4-5 ounces (113-142 grams) per week. ‡ The average breastfed baby doubles birth weight by 3-4 months. By one year, the typical breastfed baby will weigh about 2 1/2 – 3 times birth weight.
