Help! FTM

So my little guy just hit 4 weeks old 2 days ago. And he’s typically really good at waking up on his own to eat every 2-4 hours. He’s also drinking almost 4oz each feeding. So my question is, when am I okay to let him wake up on his own to eat? Is he still to small? Should I still be getting up every 2-3 hours and waking him? Hellppp meee 😅😅
