Going back to work question

Ok ladies. I’m officially going back to work Thursday

My 6 week old is bottle fed and will be going with grandma while I work.

My question is since I have to be up at 6am, to be out the door at 7:00,(I have two older kids and I have to take my youngest to school first. I have to be at work by 7:30. ), If my LO is still sleeping at 6am, do I wake her up and feed her to start the day? Or let her sleep until she gets to Grandmas and then when she gets hungry there, she will eat?
