Please help

I am a first time mom. I feel like i am not doing very well with scheduling. I do have a bedtime routine. But I see alot of mom's having real schedules for their babies. Does anyone have any tip?

He goes to sleep around 9:30-10. Wakes up at 2 to eat. Then at 3-4 and wakes up at 7.

We have play time. Tummy time. Then maybe after two hours he falls asleep. He usually sleeps when he needs to because he just crys, screams and gets scranky. I really need some advice. Please and thank you.
