My son is 22 months old. He wakes up around 7:00-7:30

I want to start waking up before him so I can get myself ready without stressing about him.

I need some tips on how to wake up early like 6:00. I know for some it’s not early but he still wakes up 1-3 times during the night so I don’t get a full night rest. I’m also 11 weeks pregnant so I’ve been sooo tired. I need tips on how to not dismiss my alarm clock and just wake up when he does. Because that’s not working with us. Also, coffee is off the table for me. I’ve been grossed out by it ever since becoming pregnant again. Thanks in advance.
