Bedtime routine advise

Momma H 💙
So currently our bedtime routine is bath songs books boob bed. Do I Need it to flip to boob bath songs book bed? He goes down so easy with the boob like it's no fight at all to get him to lay down and put himself to sleep and sleep all night the boob gets him all calmed down and sleepy. Is it bad if I just keep it that way? will he need a bottle or something to be able to fall asleep after we're not breastfeeding anymore at 1? I hate being so confused worried and stressed over everything. I feel like I'm ruining my kid.
