How many oz of formula (or breastmilk) did your 3 week old drink? I feel like my baby is eating a lot! He's at almost 4 oz every 3-4 hours and will be 3 weeks old on Tuesday!
That's about right . My doctor tells me if he's hungry feed him . I've never worried about over feeding my kids . I always would rather have them be chunky than starving them to what most doctors would want them to eat.
my son ate from both sides and I would still give him formula if he was still hungry doctor said that if he was hungry then feed him
