Feeding schedule

Mommas my 6 week old. Is starting to sleep more at night. But it does take me a while to get him to sleep after his last feeding. During the day I usually do 3 to 3 1/2 hour feeds at night I do 4 to 4 1/2 well that’s the time he usually wakes up. I do 4 oz both times. But like I mentioned it takes me a while to sleep him with the burping an all somewhere between an hour crazier fussier nights 2 hours. But does sleep 4 hours so he goes around 6 hours without feed and when he wakes. I feel that when that happens 4 oz isn’t enough should I give him more since he went more time without feed? I’m a first time mom
