Sleepy Baby

My little girl is 6 weeks today. Although she is slightly more alert than before her one month mark she is still a "sleepy baby". Trying to use this app to track better but she goes to sleep about 11 or 12 am, will sleep about 5 hours straight, wake up to feed and then sleep another 3 hours. during the day she naps roughly for 2 to 3 hours at a time and has periods of awake time of 45 min to an hour. She is strictly breastfed and is gaining weight appropriately. Just want to see if anyone else's baby does this. Also with this type of sleep schedule how do u guys fit in tummy time/play time? I feel like by time she is done nursing and having diaper changed she is ready for her next nap.
