Sleep schedules

Does anyone know of a good sleep schedule for 5 month olds? I have multiples so I like to keep feeding/sleeping time the same. Right now I don’t know what time of sleep schedule works for them because I try 5 naps a day and it seems like by the time they go to sleep they have to wake up again but when I tried 4 naps a day they were soooo tired.

And yes I have tried reading into their tired cues but if I did that they would sleep all day, their eyebrows are always red, they are always yawning and they sleep with their hands up by their chin but they also do that when they are hungry. Anyone have any suggestions?

Our wake time has to be 5:30-5:45 because I have to go to work and I take them with me so I get them up about that time so I can feed them at 6.

Feeding times are 6,9,12:30,3,6,9,1 am (sometimes)
