napping

My LO has been cluster feeding the past four days and would not take a nap longer than 30 mins once a day if I was lucky... now he was up from feed to feed (3hrs) earlier this morning but has napped the entire time between feeds since. What in the world kind of schedule are we on now?!  I'm just feeding on demand, usually will make sure he goes 2 hours before feeding again unless he is really acting hungry. I don't even know anymore 😂
