Bedtime advice


I need some advice for my 5 month old. We have a routine of bath, lavender massage, bottle, book. We struggle to keep her awake until 6 on to start the routine. I do a nap at 430/5 just to get her there and she naps for maybe 15 minutes at most, I try for longer. Every night it's the same thing, she screams and screams through our attempt at a book and we spend an forever trying to get her calm and to bed. I feel like if she went to bed at 5pm she would be so happy and it would be easier... But then she's going to be up so early, she's already waking at 4-430 every morning. Any advice?
