Change in wake up time - way too early!!!!

Over the summer, DS was waking up between 6:45-8. Last week, it got moved up to 6:15-6:20 - not the end of the world cause I'm an early riser. Starting Tuesday though, he's been up at 5:10-5:15 - it's making it very difficult to get ready for work; he is so clingy. I tried to make him go back to bed and he starts screaming: I sleep in mama and dada's bed. What the heck - he hasn't slept in our bed since he was an infant. Any advice?

FYI: he's 2.5 and goes to bed at 7:30 with no issue and takes a 1.5-2 hour nap without issue (goes down between 12-1).

DS1 is a great sleeper, so NOT like DS2!! They both go to bed between 8-9pm and DS1 sleeps soundly til around 7am. No naps anymore for him. Here and there he wakes up earlier than usual in the morning like 6ish for no apparent reason. I'd say ur DS is going through a phase?...considering his age.
