Puppy now waking up at 5:00 AM instead of 7:00AM

So first off this is completely my fault. Me and my parents recently got a puppy and hes been amazing. Potty trained really quick, slept through the night, and even though he is 9 months and definitely has a bit of adolescence stubbornness lol, he still is great to be around. He sleeps in my room and normally sleep from 11:00 to 7:00 every day. Both my parents are nurses and my mom has began a new morning shift and wakes up at 5:00. The first night she started the new shift I made a big mistake and let him leave the room to say hi since he wouldn’t stop whining. She would let him go potty and then he would mostly wander with her till she leaves, then come back to my room and sleep. But now even when none of us our working he is waking up at 5:00 AM every day now and sometime wont even go back to sleep. This is my first ever dog and this is definitely the first big mistake I’ve made with his training, and advice to get him back on his regular sleep schedule would be appreciated.
