Schedule for a 3 month old

I feel like a horrible first time mother to my 3 month old. I see all these other moms have their babies in bed by 7 & I’m over here with my kid getting a bath at 8 & then falling asleep by 9 (hopefully). Am I doing it wrong? Should I be more strict?? Some nights I don’t even give him a bath because I’m exhausted. Am I doing it all wrong??
