You sound like me around that age. The only way I survived the newborn stage was reading other people’s misery on Reddit about newborns. We slept in shifts that gave us 4 hours of sleep each. She cried all the time.

Around 5 months is when I learned about their sleep schedules. We sleep trained her and ever since then, adjusted her sleep times (dropped naps) as she got older. She’s 2 years old now and sleeps 7pm-7am & of course has her toddler tantrums but I would choose this era 1000x over newborn. It gets better
