Well, we only bottle feed at night for 3 feedings- 10pm, then 2-3am, then 5-6am. Mine will be 3wks tomorrow, she started taking 3oz just about 2days ago. My DH always tries to shove more down her throat hoping it'll keep her fuller longer but she won't take more than 3 oz.
I am mostly BFing but at 2 weeks my LO would take about 2-2.5 oz of pumped BM about every 2 hours if we gave him a bottle of BM. He is almost 4 weeks now and is taking more like 3 oz every 2 hours.
Re: Ounces of formula for 2 week old
DS eats BM every 2-3 hours/day and eats roughly 2-3oz each time. Sometimes he will eat more though.
Tyler is at 2-3 0z but I am trying to BF more and notice he is needing less. I found this to be helpful
