Husband does all night feeds

Just wondering, those whose baby is formula fed, any of you have a husband that does all the night and middle of the night feeds? I feel bad that my husband does all the night and middle of the night(if theres any) every single day. As my husband let me sleep and rest. But i feel like a bad mon/wife for prioritising my sleep. Just wondering if any husband out there that does it everyday. 4 months now, had a looong csect recovery since then my husband does the night feeds.
