Bottles at night?

My sweet girl seems to have days and nights confused. I breastfeed her for most the day, but between 6am and noon, daddy gives her a bottle so I can rest. It seems like after her bottle at 9:30 or so, she wants to sleep really well. I am wondering if the bottle is correlated to her sleep. When I am up with her from midnight to 6AM, all she does is cluster feed and never sleeps. Do you think giving her a bottle or two during the night might help with sleep? When she gets a good 3 oz, she sleeps well. But with breastfeeding, it’s so hard to tell.
