Early wake ups - help!

Hi friends! I asked this on AMA Monday but the tips recommended haven’t worked.

7 month old - eats 6 ounces every 3 hours (typically 7/10/1/4/7). Wake windows (when he’s home- because daycare doesn’t follow them) are 2.5-3 hours. Usually takes either 3 30 min naps or 2 30 min naps and one longer one (60-90 minutes). Bedtime 7:30ish. Sleeps like a champ but then has been waking up EVERY DAY around 5-530am and won’t go back to sleep. He isn’t crying.. doesn’t get hungry until close to 7. Just talks, rolls around, sometimes gets fussy but usually he’s content in his bed.

What am I doing wrong?? How do I get him to sleep later?
