MOTN wakings, please give me some hopes

Baby is 4.5 months old and sleeps independently at bedtime. She isn’t sleep trained and follows 2/2/2.5/3 WWs. Her bedtime is 8 PM, DWT is 7 AM.

We have been doing a routine based approach and that’s how she knows it’s bedtime and started to sleep independently.

Bedtime is fairly smooth but she wakes up at 10 PM, doesn’t want to go back in the crib. Husband holds her till 12 AM, she sleeps a little and gets up for a bottle. Finishes her bottle and sleeps from 2 AM till 3:40. Then it’s my turn to watch for her. She wakes up and I hold her from 3:40 AM till 7 AM as she doesn’t want to be put back in the crib at these wee hours. My husband and I are really losing our sanity at this point.

It’s been a day since we started the above schedule. Ofcourse her MOTN wakings are still there. She still wakes up every hour. Can someone who has experienced this before give me hopes that this will eventually work? Or how long do I keep trying before I start seeing some results?
