Who wakes up at night with the baby?

My questions is for stay at home mothers with partners that work. Who wakes up with the baby and feeds him during the night? Do you believe that you both should do it or just you and why? I wake up with my son during the night and let my husband sleep, even on the weekends when he doesn't work. I only make my husband take care of him when he's off during the day and during the day sometimes on the weekends. My mother-in-law basically rolls her eyes at the fact I make my husband help take care of the baby during the days is the reason why I even started thinking about this question. I'm just wondering because I want to see how taking care of your baby is dispersed between you and your partner.
