Newborn, is it normal?

My 2-day old newborn only sleeps 5min on her own. Swaddled. Then she’s awake crying. I latch her every 1.5-2hr (sometimes 1hr gap-cos I’m not sure how much colostrum I have..). She can latch strong (..that insatiable pain). As soon as she’s put down alone in her cot, the 5-min cycle begins. For the whole night. We are exhausted. I know it’s because our newborn is adjusting to this world and dunno about day and night. Is this normal? Cos my hubby said wanna bring her to PD again because of the sleep pattern even though her discharge results are normal.
