Schedule

When is a good time to introduce a schedule for my little one. He is just now a month old today and has recently (like in the past two days) started being more awake instead of the newborn eat/sleep/poop only schedule they start out with. Should i keep just doing the eat and then see if he wants to sleep schedule regardless of times or try to initiate one where he gets up and i keep him awake for a bit around 7 or 8am then do the whole specific naps throughout the day and then try to put him to bed at 7 or 8pm? He eats every 2-2 1/2 hours. At the latest he will wake me up at 3 hours, rarely 4 to eat.
