Overnight tracking?

Ok, so I’m trying to encourage longer stretches of sleep at night without sleep training (my family’s personal preference) We do not co-sleep. Lo wakes every 2-3 hours but she is 8 months old and is growing fine- developmentally she does not need to eat that often overnight. If I go in she stares at me until I give her the boob. And immediately back to sleep. Sometimes she’ll eat a little, sometimes it’s just comfort sucking, sometimes it’s a whole feed. So I want to send in the daddy who doesn’t smell like a baby buffet when it’s not an actual feed. The problem is I am apparently sleep walking and caring for baby because I have no consistent ability to track what’s happening and when overnight. How do I figure out the overnight patterns so I can send in reinforcements???
