how often want to feed my 2.5 month old baby? iam giving breast milk as well as formula milk

A. Babies might only take in half ounce per feeding for the first day or two of life, but after that will usually drink 1 to 2 ounces at each feeding. This amount increases to 2 to 3 ounces by 2 weeks of age. At about 2 months of age, babies usually take 4 to 5 ounces per feeding every 3 to 4 hours.
