Help please I’m new st this

Bonnie • Mommy of 2 handsome boys. Married to the love of my life with baby #3 on his or her way! Jesus’ girl ❤️

My 11 day old has been more sleepy today then usual, she’s been sleeping 4 1/2 hours at a time and I had to wake her twice to nurse where usually she’s up every 21/2 3 hours to eat. Should I be concerned? She’s had wet/ soiled diapers throughout the day so she’s definitely getting enough.
