2 weeks in and I haven't slept more than 2 hours straight in days

Is this normal? My son will sleep for maybe 2 hours and then he's up screaming. My wife is breastfeeding so I can't really do much except maybe bottle feed expressed milk so she can sleep, but then I'm up with him and everyone's tired all the time. Does this get better? I love him so much but I'm running on fumes right now.
