Newborn feeding

I am struggling a bit right now with my newborns night time feedings. He is 10 days old. During the day, he doesn’t have much trouble sleeping alone after each feeding. At night, the minute I put him down he starts fussing and giving feeding cues again. He is not a swaddle baby so that will not help. The only way he really sleeps for any length of time at night is in my arms. I am hoping this is just a phase but any help is welcome.
