Hey Tiffany,
I can only tell you that as a mom to a little one that did not nap at all, and only slept for 4-6hrs a night for almost 2 years...Yes I was super sleep deprived, but all in all thier sleep habits adjust. Also, ignore comments people make about thier wonderful sleepers as all babies are different and require different amounts of sleep.
You may want to check your routine and feeding schedules to determine if some tweaking to bath time or meal time may help keep him up later at night or even encourage a daily nap that could result in better sleep at night. However, some kids sleep needs are less. And from the sound of your little one, he is sleeping and waking and sleeping again, even has a daily nap... for sure he is not lacking. One nap is plenty too if it is for 1-2hrs, or 2 naps at 30mins-1hr is good too! Unless your child seems unable to function, has medical issues or develops/grows slowly, I wouldn't be concerned.
My little monkey at 2 1/2 yrs finally takes naps most days of 30 mins to 2hrs and sleeps from 10pm - 6am (broken, as cries out 2-3 times due to dreams or requesting juice, even though we only offer water during sleep). Oh and we are growing better than average and of course as her mommy, I think she is super smart.
Hope things improve soon or you find a solution, but whatever you do ...don't worry!
