early wake ups

How I can make my 7 months old to wake up at least 6:30-7:30am, not 4:45-5:30am. It doesn't matter at what time he goes to bed at 7:30pm, 8:00 or 9:30pm, he still wakes up so so early. I've tried different bed times, but every time I got the same result: early wake up. My husband gets home late, and I want to have some time with my husband, so I am going to bed kinda late every night, and then boom 💥 our little sunshine is up and ready for a new day, but Mommy isn't ready at all 😔😔
