Tips for setting a schedule?

M • Loving life! ❤️✌️
My son was born 7/25 and since then we've been EBF on demand. I go back to work mid October and would like to get on a more set schedule before then so I can possibly get some extra sleep at night and be able to coordinate feedings better around my work hours. He currently eats every 2-3 hours usually with one good 4-5 hour sleeping stretch at night. Any tips, tricks, and advice is much appreciated!
