Newborn sleep

Kay

i have an 11 day old and she sleeps without waking up when she's in my arms but whenever i put her in ber pack n play crib, she usually wakes up and makes sounds, then i have to put a binky in her mouth for her to fall back asleep. i dont want to have her in my arms all the time especially since i will be doing online school soon. does anyone have any tips to keep her asleep all throughout her 2-3 hour naps in the middle of the night? she does not like to be swaddled and i usually change her. give her the bottle until she falls asleep but she has a hard time staying asleep. i usually have to arrange the blanket in a way to where its like im holding her but again, she will constantly make sounds or wake herself up rather than stay asleep like she does when shes in my arms.
