sleeping patterns

My LO is 4 months old and for the past 2 weeks I noticed and increase in his sleep duration. He usually falls asleep at 1am till 9am-10:30 am. From 11am - 3pm he will take 15-25 naps. After 3pm he can nap up to 2 hrs after his feedings. During the day he will eat every 3-4 hrs, 5 oz -6 oz. Should I be worried?
