hungry all the time.....

my baby boy is 3 1/2 weeks old. seems to be eating every 2 hours morning and night, about 3-4 ounces each time. wondering if this is the right amount?? sometimes he is not satisfied with that and we give him another ounce or so. he is also staying more awake during the day between feedings now too, hopefully he will start to sleep longer at night? thanks!
