My DS is very busy and takes a loooooong time to switch off. Even with bathtime and books, he still needs a good 20-30 minutes of talking and singing (and rolling and wriggling and chattering) before he can unwind properly at night.


At that age, I remember he had a hard time getting to sleep and we started taking evening walks before bed.
So dinner, bathtime, walk, books, bf, bed. It was a longish routine, but seemed to work. After a while we dropped the walk.

Rather than goign back to him 2 or 3 times you could try staying and talking to him about his day, or singing, patting his bum, or whatever you think might work. Might end up being quicker
