Naps??

My baby girl is 11weeks, (6 adjusted) and I'm trying to figure out what you guys mean by naps. She pretty much is asleep all the time it seems. She wakes up to breastfeed every 2 1/2- 3hours during the day, laughs for a few minutes, screams her head off for a few minutes, and then pretty much goes back to sleep. I feel like she isn't really up for more than 2 hours at a time. Do I just have a super lazy baby? 😂😂 she's growing great and hitting milestones like she wasn't a preemie so I'm not really worried.
