Sleep

Does anyone’s else’s LO nap for long periods of time? Mine is 8 weeks and typically naps for 3-4 hour periods. He’s always down by 8pm for bed and sometimes wakes up at midnight or 1 for a quick feed and back to sleep, but can also sleep until 3-4 and will be up periodically from the hours of 4-7 (which is extremely enjoyable for me lol). Is this normal? Should I be waking him up from his naps? Would it help him potentially sleep longer at night? Thanks!!
