EBF sleeping through the night?

My baby is 3 months and EBF. She’s been on a pretty consistent schedule of eating around 830, sleeping until a 3 am feeding, and waking up around 7:30. I’m fine with this schedule as it works great for me getting back to work. My husband however wants her sleeping later. Obviously I wouldn’t mind her making it through the entire night but I’m curious. Are your breastfed babies making through the entire night? If so how are YOU making it through the entire night? The few times she’s made it until 5 am and I feel like I’m about to explode!
