Moms with experience, how do I get 12 month old to nap with babysitter?

First time mom here and no idea what I’m doing! I have been home with the baby for a year and now I’m going back to work and will be leaving the baby with a babysitter who does an in-home daycare. This will be quite the transition since baby has had me with her every day since she was born!

She wakes up at around 7:30/8:00 a.m. every morning, and she will start getting cranky around 10:30/11:00 and will want a nap. The only way she naps is with me nursing her to sleep and napping with her. How do I abruptly get this to end? How will she nap with the babysitter? She gets very very cranky tired around this time every morning. Any advice? When I try and leave her in her crib, she will stand up in the crib and cry and cry and not give up or sit down. She continues to stand and waits for me.

I feel like the babysitter will not know what to do to get her to sleep and my baby won’t know what to do either since she’s so used to me and my boob at this time every day.

Any advice, please! I go back to work in a month.
