Baby only sleeps 10 hours a day!

How about yours? I have an app that tracks his sleep, my baby sleeps from 9pm-6am, wakes up every 2 hours to eat. From 6am-9pm, he sleeps 3 30mins nap. One time he slept for 14hrs, the next day he only slept for 7hrs! It has been like this since he was born. It’s bad right?
