I mean if she's still hungry i would make another 2 oz my daughter ate 4 oz at birth and then 6 at two months... And then we gave her baby cereal in her bottles at night when she turned about 3-4 months.. It helps them sleep longer at night because they get fuller
My 2 month old ate 4 oz then another 4 but she slept about 5 hours and I asked the doctor and she said growth spurt maybe now she's back at 2-4 oz every so often
