Does your baby make sounds while they sleep?

FTM here. My baby is 3 weeks old and always makes little noises while she sleeps. I was wondering if this was normal. She eats great, seems to sleep well (just noisily), and is doing good otherwise. Her last pediatrician appointment was normal but I didn’t bring up the noisy sleeping thing - if it isn’t normal I will schedule and appointment asap. TIA.
