Baby sleeps independently at bedtime but wakes hourly - help!

Baby is 4.5 months old and has miraculously learnt how to sleep on her own at bedtime (8 PM) She isn’t sleep trained. We just follow a routine based approach. We do a bedtime routine that involves bath, bottle, lotion, bedtime stories and she’s calm. We put her wide awake in the crib and she falls asleep within 10 minutes. This has gone on subsequently for two nights. Even after her 1 AM feed, she’s put in the crib wide awake and she puts herself back to sleep.

But the problem we are experiencing is, she wakes up every hour. How do I address night wakings? At the moment we go as soon as she wakes up and rock her to sleep. Are we undoing her falling asleep independently by doing this?

Her approximate wake windows are: 1.75/2/2.25/2.5.
